I have similar prob,
the game freezes for a few secs in combat, and ping jumps to red.. ever since patch 242
2 dps + 2 support max btw, no need to blame all supports for one.. such as dh lol.
I was hoping they would limit the xp so we wouldn't be stucked with meta's all the time, the xp system stays the same, sadly. And everybody wants to get the most out the game in as little time as possible, understandable. But that means we will be grinding 110+ GR's for xp and gem upgrades, I don't see it will include class balance or build diversity.
Nothing but statics and twisters pre and post season, what will it be next? XP needs a limit, imho.
