I sort of agree. Specifically inside the iron dome, it is a problem (since he is kinda useless inside the dome), but not a huge one. Alchemancer is a ranged class, so he’d be most effective a little further back from the action. While a Vigilist could run up and drop a dome just to neutralize the Alchemancer, I feel like it’d be more useful for her to put it around her teammates, who would (in theory) be some distance from the Alchemancer.
On the other hand, I agree that the Alchemancer could use some sort of melee. All the other classes have the different attacks with their standard melee weapon in addition to abilities, but he just has the fireball. Maybe it’s just me, but this makes it feel like the other classes have 6 actions to choose from (slash, overhead, stab, 3 abilities) while Alchemancer only has 4, 3 of which have a cooldown.
So to summarize, I don’t think the Alchemancer should be inside an opponent’s Iron Dome all that often to begin with, but giving him another standard attack that would be usable inside would help a lot both with that specific situation, and the extra variety would be a nice bonus for his general gameplay.
p.s. Agreed, you can never have too much cowbell
