I have a L2P issue

Hi, im struggling with some things in PvP land. I usually play stamblade in BGs u see, but as soon as i meet Someone with Steel tornado and permafrost, i melt in like under 2 sec.

I have PvPed for a few years now, and this is the only situation where i actually feel helpless, and have no clue what to do.

So any suggestion?

PS. No worries, this is not a nerf thread, im well aware everything is perfectly balanced, just a L2P issue on my side.
