Why everyone so down on demons/Jurraxus

Here’s another problem with Jar (and a common trap for any auto-battler) trying to force strats. No matter how much units there are at the pool, aiming for specific strat might just F you in the butt. And Jar kinda forces you to go demons (which is not the right strat imho. Ideally you just go for whatever is the strongest with ANY hero, and heroes must be giving you some additional strats as an option due to specific heropowers. Works with mili, not so much with Jar) (btw I once lost to Jar who just went all mechs XD I got 3rd so don’t know if he won, but it was top 2 for demonless Jar).
