If the rules of TuS for TTRR from day 1 were check time by MS, I am pretty sure everyone would be fine with it.
I don't find hiding on top in Roper or notching in BnG lame either, again, if everyone was doing these things from day 1, it would be fine.
Like Rene said, blame the map/schemes, and for me more importantly is the rules and people you play with.
I believe in a fair fight, and no matter what your opinion is the objective of a League is to win, not to have fun, you can try to have fun and not try to win, you can try to have fun and win at the same time, or you can do anything humanly possible within the rules to win.
All 3 options should be no problem for everyone to accept, I personally feel that it's rules of this League and the people who play and use/do certain things to get an unfair advantage, that is lame.
For example, if I was playing a TuS Classic 1v1 BnG against some guy who only joined TuS let's say, an hour beforehand, knowing full well that I could easily win 200-0 without notching or repeating, if I chose to use my notching abilities and repeat shots against the opponent, kill him in 6 turns or something, I don't think he would have a very good experience of the game, and even if he did enjoy it, I would still consider it lame because the guy probably thinks I am god or something and all I done was "notch" some 4s FP nades which is one of the easiest things on this planet to do...
But if I was playing Mablak, and we were both notching, both aiming to win, both playing within the rules, what's the problem? It's a really fair fight...
I'd hide on top in Roper against Mablak because we are both very good Ropers, and just securing our lead regardless or luck/mistakes.
I wouldn't really do it against a noob though, i'd showboat a bit and show him it can be fun while he learns to become pro, THEN he can play serious, or not, whatever lol.
If I was to play TTRR against Mablak, and I done 45.56 and he done 45.78 I would consider it as my greatest achievement in TTRR and I would be EXTREMELY pissed off if I had to play him again because some people around here just can't be assed checking a replay...
Shouldn't it be the main purpose of a League, to make sure everyone can enjoy equal competition? The rules make certain players able to get an unfair advantage over other players, regardless who feels what, this shouldn't be tolerated with being a League.
I am guessing anyone on Earth who for some reason suddenly decided they wanted to find out who the best players in the world are for Worms Armageddon, they would come to this very website to find out, because the best of the best play and compete against each other here seriously, if someone asked in #AG "What's the best League to play WA competitively?" I am sure everyone would answer "www.tus-wa.com" not "www.letsallnotgivvaf@#!aboutwinningatwa.com".
Edit: I honestly think, if you can't be assed checking a TTRR replay that takes 1 or 2 minutes, then you simply don't care enough about winning, and if this is true, you certainly shouldn't be wasting your opponents time who actually does take it 100% serious, maybe it's a tiny little bother to check replay, but think about your opponents who are innocently trying to be the best competitive players at this game...
You are literally choosing and holding your own agenda over the truth and reality, that is selfish.
