lag/latency

hello,

i have high latency peak then disconnection or have to wait to end of the latency peak to play again. I can't say it's strictly cyclic as it depends of the environement where i am. Generally speaking, latency peak from time to time in world zone and bgs, increasing in AV but very high when i am in wintergrasp, so crowded place ofc may play a lot on the desync i get.

I would like to know if others are experiencing this issue as i don't experiment this issue when i play on outland. So it mays become from my ISP because i play on wifi...and my config is not up to date as well. Plus, i don't remember i had this issue when i was in wintergrasp one year ago when i played another char...

last wintersgrasp was almost flawless, i don't understand...
