Brazilians use the EU ruleset aswell afaik.
Pretty much everything you said is correct, however there are a few things I've found rather neat that ESEA/CEVO does:
•2 Halves, makes things even, allows both teams to have a break in the middle, switch sides, and take a break for bathroom or to go over strats/important game issues they are having, or just generally relax a bit.
•'.ready' System, makes things alot less complicated and will insure that nobody won't be ready at the start of the match, The 'live on 3' system is also a neat feature imo.
But if I'm not mistaken (not 100% sure) the Asians have created server plugins that does the above and other features like showing score and time on the beggining of every round, they did say they're going to release it soon enough to the public, so I hope ETF2L adpots their plugins.
I think that i49 gave us the best show that we've ever seen, every match there was incredible to watch and they were all played on EU rulesets, the NA players who have been to the Insomnia LANs should express their opinions on this.
One thing is for sure, a universal ruleset will be a great thing for the game.
Sorry if I got sidetracked from the topic.
