I never said 'T1E is objectively the best system ever devised on god's green earth'. Everything I've said has been my opinion. Did you go to Dazsos' strawman school of debate? If that's all you had to add, feel free to walk back out the way you came, Enki.

That being said, every other form of combat balance I've seen has been exceedingly poor. Only T1E completely negates power creep, balancing out fights without the need for dice rolls or coin flips. It is in my opinion the best method of control for a ranked (AKA a competitive) setting. Cool-downs are unbalanced for fighting because the penalty comes after the pay-off, it's like the difference between solar beam and hyper beam, one is objectively better than the other. If you kill your opponent it doesn't matter if you have to wait a turn to charge afterwords, if you have to wait around and do nothing for a turn before-hand your opponent can see it coming and get a hit in first, better balancing the fact that your ability is OP.

Mana pools have the same issue. People seem to expect fights to last forever and badly balance their mana so that they're really never at any risk of running out. 

There's a reason, I presume, why T1E has lasted for ten years and still sees regular use. Not to mention, if it's the most restrictive system and I still kill -everyone- using it, god knows how easy it would be for me to ruin people when I wasn't restricting myself by using it.
