I am not sure if/where this may have been suggested before but I figure it is worth mentioning/bringing up again.
Enders goal with MC was to try and bridge the gap between new and established clans, while also increasing the competition at the end of a month. The biggest barrier between these two types of clans is their access to dumpers, which have essentially permanent use of fight speed + energy buffs. Adding a multiplier to energy gain actually provides these established clans with a bigger benefit than newer competitors as dumpers will get the additional multiplier of fight speed on top of more energy gains. Additionally MC doesn't actually "feel" like it is building up during the month, as the only effect is multiplying the amount of energy you gain from a fight.
This is why I suggest changing MC to a non-stackable fight speed buff. Not only will this bridge the gap between clans with dumpers vs those without, while still allowing established clans to get more benefit from their dumpers earlier in the month where MC offers less value than a traditional fight speed buff, players will also "feel" the crescendo building, as fight speed is overtly noticeable within combat.
The main point being established clans aren't able to double dip on an additional energy gain multiplier and fight speed simultaneously, this lessens the gap between established clans and newer clans as a month progresses, while dumpers still have a benefit over the competition but are more useful at the beginning of the month (still probably faster overall).
Furthermore fight speed is beneficial for all types of play, except some niche onlining situations. This buff would then be useful for energy bots, leveling bots, kudos bots, building bots in general, etc. Which I can see having a positive impact in overall engagement throughout all aspects of the game.
