I don't want to see what could happen with Sion lvl 1 with learned E + 0/21/9 + smite +  flash (practicaly flash with 100 cdr + broken finger = instant teleport). Even doom bots or URF were balanced compared with it

But yeah, a gamemode with 10x bonus masteries and runes should be fun, broken, but fun

And offensive tree.... mmh, i don't know, i thought should go nicer, but the math with the other trees leaves it practically pointless
