Tried CTM, works perfectly

As Matenia said, from their website
I'm quite surprised they would use a wotlk client for a TBC server and I'd be very curious to know what these "patches" do exactly.
As for the Wholesome TBC Fight class, I can confirm that it works on a regular wotlk client. No idea about the endless one. You should probably test it with the trial version.

New endless TBC is comming out in a few weeks, does the bot work there?
They have their own client you need to download and play from.
Just making sure the bot works with that or if they can detect it

It's going to be a 3.3.5a client, so technically WRobot should work.
But you'll have to rewrite everything made for TBC to work on the WotLK client. 
It's going to be super interesting, because modding 3.3.5a is much easier than 2.4.3 (I've done the latter before to rebalance TBC, added new maps, spells, etc - it takes forever and there are basically no tools unlike 3.3.5a). But it's quite possible that if they are skilled enough, they can definitely break WRobot through Lua changes. They can also implement new anti-cheat and generally better anti-cheat in 3.3.5a.
That being said, you'll have to test it. On the bright side, the way my fightclasses are written (and Wholesome TBC as well, from what I can recall) they should work on 3.3.5a clients, even if they're made for TBC.
