I went 28/5/11 in my first game of tryndamere...my team still lost, and I don't think trynd is op at all. Honestly, some heroes are just easy to use.
I suggest Turning his mocking call into a summoning ability that summons a chick that pecks other heroes for 1 damage, and has 1 life, and can easily be killed.
Of course that maybe be too OP as well, so well just give the chicken a debuff that when you spawn it it loses 1 life.
Seconds his spinning slash i mean wtf IT DOES DAMAGE? my gawd is that OP. lets make it fan off other heroes and cool them down, thus healing them isntead. Call it fanning slash.
And holy **** his ult, lets turn it into you die in 7 seconds, with no buffs. doesnt stop you from dying, just kills you if you use it after 7 seconds.
My gawd was he OP before those changes, now hes ok.
