Ye 38lv people on Heiron with full greens~hardly a few blue gear will have pve mode off to get raped by 40lv twinks running with +10 gold weapon/gold gear , ok.
And the 38lv will see the twink , the twink/rifter won't be able to attack him cause of pve mode and the 38lv will inform his mates or on /3 where is the rifter and the rifter will just get pwned all the time by 55s.
But of course there are solutions for that , like macro macro and macro. Also , okey you get pwned for one time and that's it next time you gonna activate pve mode , and done. Better way to farm AP , farm on Ingrisson/Gelkmaros no point to rift lolz.
