Obviously side effects such as toxic and burning needs to be fixed, especially in melee. 2 light strikes into full toxic dmg bar which drains full HP bar over time and even kills after revive is just hilarious. On burning crozius arcanum as well! Furthermore I still wait for elder tanks to be fixed in it's mechanic. At least some speed should be needed to calculate hitbox collision. And pls don't let them drive sidewards...
In the near future? The free unlockables for Eldar visual customization. I don't think I should feel bad about wanting a lot of that stuff for free. Eternal Crusade is buy-to-play, not free-to-play, so most of what's available shouldn't require an additional purchase. In the long-term? Playable Sisters of Battle. : D
Melee balanced. Melta vs vehicles balanced. War campaigns. More subfactions differentiation. More of everything: weapons, items, maps. More wh40k stuff: bikes, killacan, dreadnoughts, defilers.
More melee weapons and types of for Eldar. Wouldn't mind more maps, but they're currently big and pretty enough that I can wait a little longer (plus it's not like I've explored every nook and cranny of each of them or anything).
The inevitable death of the toxic element of the community. When they finally get bored of flaming and leave the forums so we can actually discuss the game. Game-wise? Garrison hub. Optimisation. Bug fixes. More customisation options.
