I dunno if you have seen a Bosswolf minion, but even a single minion at 288hp is pretty darn frustrating to deal with.
Then the emblems to beef up the stats… It’s all in what you make of it. In this case, Bosswolf is a meat-shield and this makes him meatier and shieldier…
Have you even seen the Barbarian skill? itty-bitty damage over 5 turns. I would argue that is worse than the Druid talent. I would even state that the extra “meat” added by the minion is almost as good as the fighter’s revive skill. If it can keep a hero alive with even a fraction of HP left, it can fire a special and turn the tide.
Inari’s minions are the only ones that do any sort of good damage. Beyond that, if you are counting on minions for damage, then you should probably reassess your lineup a bit.
To the OP, however, Fighter is one of the best when applied to a healer. Delilah is queen in this case. But if it lets a fully-charged hero get even one more special off, then it is worth it.
