More often than not, anchors in this game have the tools equipped to annihilate FB users. Shen, you aren't laming him, hell he can actually lame you out as your FBs do nothing to him. Hwa Jai, when he has Drink, which he will if you are content with laming out, will let him in for free if you throw a FB, hell even if he isn't Drunk, he has C Dragon Backbreaker. Vice, no way she's being kept out that easily. Elisabeth, isn't happening, Clark can get in, Ash...well Ash will out lame Kensou. Kyo can pick his spots to get in.
And then once they're in, then what? Yeah, having the Command Grab is very nice for punishing unsafe stuff and gimmicks but of the above...only Hwa Jai has a move you'd legitimately eliminate from usage thanks to having the meter, whereas on the flip side, they gain more options against yours when THEY have the meter.
Having more meter for Corner Throw combos is somewhat nice, yet ultimately not that big a deal since past 1/1 or maybe 1/2 you aren't getting a ton more damage. And you can get those meter numbers just as easily from Point or Stopgap. Same deal for having more meter for that DP combo.
As for meter for his HD combo..so what? Unless you're extremely adept at the DP>j.QCB+C, run, DP loop, you need the corner to do your solid damage, solid damage that a lot of better anchors can do from anywhere without nearly as much execution. Without it, you're best at using 2 meters for 700+ damage which is great...especially since he can do that yet again from the other two positions on the team.
As for not liking him as a point character, that's fair enough, but let me make my point. Kensou works best when his options don't have that many answers. For most characters, the more meter they gain, the more answers they have to Kensou's options, and more often than not the options Kensou gains still lose to the options he starts to lose. With meter, Kensou's only changes in options become his EX FB giving him a slightly better FB game, and his Command Grab DM which is good, but still pathetically ranged limiting it to punishes really, and both ways, he can gain them quite easily from point position.
In the end, for deciding whether a character is a better point or anchor (as pretty much any character can be a Stopgap) it goes like this. Do your options and damage you gain with the extra amount of meter outweigh the answers your opponent can now gain to you? In Kensou's case, the answer is honestly no. His options don't get that much better, and his damage pretty much tops out at 2, maybe 3 meters, which again, he can get at point or stopgap.
Kensou CAN work as an anchor, but ONLY if your team really has absolutely no other answer at that position or if he needs to avoid matchups early. However, considering to really become good at this game you need to be able to be adept with no less than 6 characters, that should never happen short of messing around or predicting matchup problems.
