I started using Arachne for the first time yesterday. The single target damage is absolutely ridiculous. I went 24-4 in assault because they had no way to avoid me blinking past their guardian and wrecking havoc on each mid to back liner. I did like 65k player damage.
I think the item changes were a little short sighted, things like some tier 2s being more powerful than tier 3s with NO cost changes, and stacking items, especially Devs, feels like a joke with how weak they are when you first buy them, without much of a payoff once they're fully stacked. On the whole i think the game feels better overall because of them and tanks are much nicer to play without being truly unkillable, although i'm sad to see that builds and the meta god choices have barely changed at all, at least so far. That's about all i have to say about it despite the hugeness of the update.
