Spirit Walker Twister vs. Arbiter of Ash

Is this not the worst experience in the world? The whole time I'm playing this build I'm frustrated by how terrain-gated twister is. If I'm doing a desert map I'll send out 100 twisters but I won't see any of them ever again. Not to mention if I don't have the damage to out dps the boss the twisters make it practically impossible to see anything so I couldn't genuinely interact with their fights even if I wanted to. AoA fight is just the culmination of everything I have about this build. If anyone knows what I'm missing please fill me in.
