After a few games and much reading of forums, I've this view on the new rules.

Clawpomb has its good points:
-There is not a dominating 1st tier basher inpervious to damage at high TV.
-For (Claw)Pomb you need 2(3) skills and strenght(mutation) access. And most teams have some players with Strenght access (2 doubles for elves... like old Chaos and they get Jump up easy)

This, coupled with removal of aging and nerf of DP has changed something I strongly disliked:
-Cheap lino with just one skill is no longer one of the strongest weapons in the game. Teams were build around that simple principle, and some games just revolved about it.

Still some valid concerns:
-No more positional bash. But I think Dwarfs can do the trik, just that instead of MB+Guard and couple of DP it's MB+Guard and some Fend with couple of PO and DP.
-No tough team that is resilient enought to casualties... well, that's not too bad imho, and there are Undead.
(Just that those 2 are probably not tier 1 at high TV, good)
-Finally one quite tricky, minmaxed killers at TV 1400... I've a sugestion below.

I've seen several proposed houserules. But I don't likehouserules and less at this point (too early, imho not a real effort to adapt to new rules, not enought consensus)

What I'd like to see first if PO (or any other combo) is truly overpowered are changes on BBox division management (looks like it's mostly a BBox issue, we'll see League) like:
-Bring back TS (DP had a huge penalty).
-Remove BBR or use it for the scheduler.
-Remove (if it's still there) the anty-mirror games factor.
-Add weigth to the racial factors.
-Bring a racial ranking for the BBox (encouraging diversity, less density of killers=lesser impact)
...and then, if nothing else works, do the houseruling thing.

CRP is not perfect, not nearly so, but I kind of like it.

Note: those are not sugestions for discusion, that are best left for forums, just my view at this point... still, feel free to comment, I'll be glad to read.
