If you want this game's mount, Hollow Ichigo, to be just like Kyuubi, then yes you should add in the feature.
If you want this game to be a little different from SL then I will have to say no for the addition.
I say no with the addition.
SL has become a game where there are many strong players and at times it was a ease to swift through gaining levels. Now though, with the new stats being implemented some, maybe many people, will feel that the game is getting tougher. That is just what the game needs, a little more toughness. Personally, without my kyuubi, the game is getting tough for me xD.
Although, with the new KG system, I think that in the future SL will see strong players, maybe even really strong, who knows.
I would like it is this game remains a challenge, but sometimes it would be nice to have a break.
After my Hollow Ichigo is gone, LoB will probably get harder for me.
