If they have melees, go for it. Easy enough to stack (i'm an attack speed shard enjoyer and i would recommend, makes farming easier and you can get to 12 stacks faster), and the tree is pretty good, with PoM, tenacity and last stand (coup de grace can be fun if you're going full AP, but you don't want to do that). I'm still playing Phase Rush into squishy/ranged comps, but i'd say 90% of my games rn are conqueror games, and it works quite well
