The battle servers aren´t about teamfights.
They are about fights like 2 vs 6. Many of them.
Well I can actually handle 3 players who are worse than me when I´m playing in my black gothic plate with my 12 agi, but it´s fucking hard to not gekt rekt cuz u only need one retarded swing, one wrong step or getting a knock down and u´re dead, no matter how many hits u can tank.
I tried like all builds with all types of armors. Right now I´m trying what I played ages ago, so a balanced build with my kuyak and actually it´s better than plate and agi, cuz u are fucking fast and u deal ridiculously much dmg, well u die most of the time after the 3rd hit, maybe with some good footwork u can tank 4. Compared to my old build this is shit cuz I tanked most of the time more than 5 hits.
But at all for every build but a str build I can only recomment medium armor - 13 - 20 weight - cuz the reductions when you play plate with a balanced/light str build are way to hard to handle them
Just saying, with my 33 12 and black gothic plate I had a kd of 2,7 (played mostly siege, so after 208 mio I had only 2k kills on battle xD) and now with my 24 24 and medium armor I got 3,5.
But Heskey I gotta agree there, in a complete teamfight plate wins allways!
