Summoner has ranged attacks.
Zerk has BG HP Buffs all the time now, so massive HP to wear down.
My 120 Summoner was in battle against 120 Zerk today in RvR, and i got killed after protracted battles, but had to fight off a bunch of swarming high level Sorcs at the same time, so was halted half the time. I had 12K+ HP, and the Zerk had much more with the BG buffs. Not conclusive in this situation.
Earlier same day had a 10 minute stoush with a similar Zerk in BG, and eventually lost that one as well, but he bought in a 103 Sorc to help him out. They travell in packs
I had no such support going, and no party buffs. To be continued, particularly after I finish my re-build in a week or so. Been out of action for a Month with Suit Bugggggg.
The above listed battles are not indicative really due to the un-readiness of my summoner and the 1 V a bunch situations, but I was happy with the way i totally tanked for ever and at one time had the 120 zerk on the ropes and on the run with very little HP on his bar regardless of the hits i was tanking from the rest of his gang.
