Personally I think tanking is for weak minded people who look at something and say to themselves thats too hard so I am not going to try.
I 'm an old player, I don't like the new version of T11 and not ineresting to play in other competitions except associations with a company of friends who still playing the game.
No, I haven't a super-tanking team, we are not in top 100, just a team with 6-7* players and I use "wall" formation to stay in same League.

If you can give me the option no to promote in next lv, don't know how, maybe not participate and have 0-3 in every game, I wouldn't mind with any suggestion.
