What are some things you would like to see added to Fyreslayers? In particular, things to differentiate themselves from other factions (or even other duardin).
Given the nature of Slayers and the whole motif of Fyreslayers, I would think that they are a faction that will typically not utilize artillery and instead rush into battle. That being said, I think a focus on maybe one or two units of calvary, perhaps fyrelsayers riding on mini-salamanders or something, would be neat.
Also, maybe some more units that buff other units through runes (like prayers for priests) would help resolve the classic dawi problem with wizards.
In general, like all AoS wave 1 factions, more of a selection is all I'd like. Fielding 3x30 blobs is not what i consider fun.
