Tomislav is the right answer, everybody knows that.
Marko the Wacko? Absolutely not. Here's why:
All the players who would have given him a match were already gone. I dont see how the following players wouldn't have been as good or better than him (Awaz, Joku, Kane, D0wnstyle, W0nna, Sovsordie, Veg, etc.) I bet they prolly barely know who marko is.
He took much more time to improve than most top players. If I was a huge qmer, he certainly came second place, with maybe 1500 qms every month, using 9 different nicknames and who knows.. perhaps even more. Indeed, he played / ruled for a long time. I just came back on the forums, and surprised i am not to see he's still there.
I remember Tomi could beat me 2 tanks vs 5, he clicked every where like a god. Rumors said he had high tech equipment, but the skills are amazing still. Tomi did have something in common with marko and all others tops: he sucked big times on naval maps, cried every time the map would pop up.
I dont think who is second best player matters, because there's a long way between that person and Tomi.
