what andy's saying is time has nothing to do with how long a fight is, it could take an hour.
The cap you are referring to is a round cap, after 30 rounds if you don't kill the defense side you lose by default.

What he meant from dawnseeker had said was tynon isn't going to remove the cap because they want a more offense themed game, not just tank queen and khan as much as you can even though thats where it stands atm, but i digress.

If you're hitting the round cap a lot you need to up your offense, you're not doing enough damage, I'd advise to get rid of bry, she'll do nothing for you damage wise and you shouldn't need the stuns with khan an queen soaking everything up. try perhaps blood or gen alci where she is and get rid of the casters asap and you should be good

Edit:

I had used
x/x/x
Herja/x/main (sub Khan)
Gen Alci/Lance/Queen P
Around 170 i think it was
