Well there are several things to be said of this. Old Gigantti was really good, first of all. Secondly, Gigantti has a highly-regarded coach with a reputation for developing talent. Finally, some role swaps have been made (which relates back to the coach being able to develop talent). rCk, who has performed wonderfully on D.Va as an off-tank, was a DPS while on ENCE.

ENCE struggled to beat many of the players currently in Contenders, but it seems clear they have all become better players since those days.

Also ENCE did beat Gigganti in the first Finnish Championship, with the old rosters

You are both right, it's just that pessimist in me that always comes back to the surface. :)
