actually i didnt land stun on your during lion heart, everything was resisted, but sure, once CON is fixed, i am up for round 2 (right now when i meet high lvl con class, the stun is joke
depends how fast can u notice him and start kiting he isnt that much faster and well, u gotta use the hills a lot (especially ones which have tricky path to get on them its big help if u know some shortcut on some hill and he doesnt ) then also if u have big enough rock, depending how good u are on the cutting corners and how bad gladiator is, u can easily kite people even with 20 more speed around this obstacles but yeah, gladi is one of those harder match-ups
