I’ll say right away, I average skaven enjoyer and I think that says it all.
The game mode is cheerful and fun, especially for the Skaven, it creates a good space for co-op on both sides and for many it will give a second wind to play the game.
Among the problems:
Basically, the Skaven are much stronger than the heroes (of course, if the “heroes” are not a squad of 35 levels) and defeat them at the initial stages.
I don’t know how to solve this problem, but intuitively options with a slight increase in the characteristics of the heroes come to mind.
I can also note that the Skaven Flamethrower is too weak a class, since it deals very little damage for a very short time, often dying from shots “by touch” through its own stream.
I would suggest increasing the strength or duration of the stream.
There are many places on the maps where the Skaven cannot climb, although they are not particularly inaccessible.
What to do is clear.
I would also like to separately suggest introducing a parallel mode of games for only one side (heroes or skaven) and adding the ability to play with bots (in fact, of course, for skaven).
Yes, it is clear that probably due to the interest in skaven, games in such a mode can take a very long time to find, but in this case, nothing will stop players from simply going into quick matches with the usual mode.
In any case, the impression from the new mode is very good, I wish the developers further success in its development!
