ToME: the Tales of Maj'Eyal

New player, I'm trying out brawler and looking at information on the wiki and here, but it seems like the "Brawler revolve around skill", Relentless Strikes, was replaced by Axe Kick. How significantly does the change game play and how do I avoid screwing up my character?

Just do it.
Brawler show itself as capable class even on Nightmare (died in grave during 100 turn siege).
Urkis died very fast, I was surprised.

edit:
brawler is awesome. He show he is more capable than Oozemanser lol.
Died in Farportal from elite with Inner Demons, and I almost kill him.
Don't know what other class can do with this on Nightmare.

And this is the ONLY class in my experience, that survived Dreaming Horror Dreamscape, and killed DH after it.

Well, I start to think, that it is impossible without already prepaired gear in Yiikgur vault.
Without Untoucheble it's just a pure waste of time.
And it's good if you have tier 5 armor with max defence.
