Per this question here, I asked about grappling hooks as a weapon in D&D 4e, and the community came up with a great answer using cahulaks. Now, as stated in my previous question, I'm trying to homebrew a race whose primary shtick is the use of grappling hooks and rope in all of their endeavors. So this is mainly a balancing issue.
The three feats described in the accepted answer in my previous question, (Cahulaks Novice, Cahulaks Specialist, and Cahulaks Expert) all replace a character's attack power with a power associated with the use of Cahulaks.
Would a race that gave one or more of these feats for free be wildly out of line with the power levels of other races?
Would a race that gave one or more of these feats and did not require losing a class attack power be even more so?
