Also playing with ash now, his units are summons that makes him totally unplayable. All the abilities to counter summons out right now and investing all that nora for 3 units 2 of which could be popped right away is really bad.
I hear ya. Disbelief, shatter summons, etc. This part make it's a little risk but that's what game is about. If people ran ash more there would be more anti summon abilities in the Meta.
Ash just isn't worth the investment unless your playing noobs, most good players will get rid of the summons very quickly. He'd be best to lose split hero, become a full faction hero. Lose marauder or have it changed. If deployed in ud get the mercenary if deployed in k'thir blademaster, drop the cost accordingly, if split between the two random drop of 1 of them.
Considering that BCS is an auto in literally every FW bg (and BCA should be), I think the meta right now is fundamentally hostile to the kind of large individual summons that Ash produces. That's a big guaranteed chunk of the field.
