Overall there are some LTM’s that are impossible for free players and there are some that no person would spend gold on for the rewards.
Stronghold LTM - I think all active players should be able to achieve in its current state.
Alliance war LTM - I think a lot of players use alts to get this LTM completed, although there are some honest players left. If you are on at the beginning of the event, you can usually complete this LTM; if you start hunting with the event half over, you can spend hours scouting and missiling to find little or no battle points. I don’t really have any suggestions for this, other then removing the event due to players hitting alternate accounts.
Tower of Strength LTM - I think this LTM is almost impossible to complete if there are more than 1 active alliance in the league system. I would suggest a battle point LTM to go along with the tower of strength LTM
Train Unit Value LTM - Any player with instant build can complete this without spending gold. If you do not have instant build, enough units can be queued in factories to complete the first couple of levels. This LTM increased in difficulty substantially in the last year. Overall I don’t think there is an issue with this LTM, other then the rewards.
Merge Max Level Commanders LTM - This LTM is ridiculously difficult. I have never completed it before due to the rewards not being equal to what you have to spend to raise commanders levels. I would recommend reducing it to lvl 1 and going up by 1 per mission, for maybe a max of 10 missions.
Bootcamp LTM - I really enjoy this LTM, it adds a mixture of requirements and actually requires people to do different things instead of clicking the same buttons over again. hitting 50 NPC’s is a little painful, but overall not that difficult. I would think any active player could complete this with spending some trainings, and a couple speedups. Overall I don’t think there is an issue with this LTM,
Warzone LTM - I don’t think most free players complete this one, as it requires you to buy items or have received items from a purchased bundle. I again like the concept of having to do different things, but using items/gold, just to complete an LTM is wasteful for most players. I am not going to use a catalytic injection or advanced deployment if I don’t need to. I would suggest changing the requirements for this LTM.
Weekend LTM - This LTM becomes difficult at the warcom trainings. Most free players don’t have the trainings to complete this, and the last couple of levels of adding experience to a specific commander is not great, as well as merging a specific commander. I would recommend changing the warcom, experience missions, and merge missions to something else Maybe a battle point mixed in with the others.
Box Event LTM - This one is pretty straight forward. any player can get to 5-10 without spending gold. I don’t think there is anything else to do to this other then maybe adjust the drop rates for the box to make it easier.
Gold LTM - I personally don’t do this LTM. I am not going to spend this much gold for the rewards that are dropped. The amount of gold should be reduced by a lot.
Raid Players LTM - I think most players use an alternate account or a friend to complete this LTM. Overall, I don’t see an issue with this one.
Global Domination LTM - The overall points LTM seems to be ok for an active alliance, but may require some gold to be spent. The wins in a row is more difficult, but can be achieved by an active alliance and some gold spending.
Global Conquest LTM - the personal LTM is impossible without spending gold. a free player can get maybe half way if they participate in every battle. This should be adjusted down. The alliance LTM seems to be ok for an active alliance, but I believe still may require some players to spend gold.
Research LTM - A lot of players are done with research and miss out on these rewards. I would suggest giving players the option to do an either/or situation if they don’t have any research left.
EXP LTM - This LTM has increased in difficulty in the last year. The rewards do not compensate for the amount of trainings that are used to complete it. It should be adjusted down.
Campaign LTM - The LTM themselves are ok, the one on Monday’s can be completed without spending gold if you dont waste a lot of energy. The one on Thursday cannot be completed due to less campaign points in admiral base II. I would suggest changing campaing points on admiral base Ii to the same as admiral base I to allow free players to complete this one as well.
Overall i would guess half of the LTM missions can be completed by an active player, and the other half require either too much gold/items to be spend to complete them. The rewards need to be increased for the more difficult ones and/or the difficulty reduced. I think a good ratio would be having 75% of the misions able to be completed by a free player and 25% for spending some items/gold.
