On the server most of us are, Celliar Lake, there is one single whale with a PVP oriented team — and he stands high and above everybody else. You really only meet Bozel based pvp teams everywhere. I met a few non-whale PVP dedicated teams as well, but those hardly posed much treats without maxed gear.
The arc is one of my favourite accessories, and it sure could fit well Ledin… if Ledin wasn’t one-shotting most of the lunatics foolish enough to attack him ;)
I like to put mine on my spellcasters: in my experience, it helps them sustain damage quite a lot (they get hurt a lot, so they hurt a lot back, and since usually they are killed because their troops can’t deal counter damage, I am guessing it benefits them and their survivability quite a lot).
That’s in the case they end up out of your tank’s perimeter for some reason, of course, so it’s very circumstancial but still an endearing little accessory.
