1. As it should be, agree.
2. An understandable limitation, if not only because VERY FEW Shinigami have more than one or two abilities anyway. It would make it more interesting for Shinigami against Vizard too, agree.
3. If they only have one, could it be an extremely powerful ability? Just to clear things up. If so, agree.
4. I disagree here, and i'll give my reasoning on number 5.
5. I also disagree here. The Vizard's mask shouldn't have an increased cooldown, it should have a lower duration, and can only be used for 'x' posts per topic. I can't remember by name, but one of the Vizard was told to take their mask off and save it for later. This suggests to me that once the duration is up, it's up for that day. As for the question 4, the reason I disagree is this: Vizard ARE a superior race to Shinigami when their power is at full swing, and it should apply. However, even if they are a superior race, that is only in potential. The mask + Bankai should be able to be used, but only for a very short amount of time. In fact, I suggest that using Bankai lowers your mask duration by three / four posts automatically. For example, if a Captain level Vizard has 7 posts of mask time, using Bankai would reduce it to four. That's effectively around 4-8 attacks, in which time if it runs out, they are screwed. If they've already used their mask, removed it, used Bankai and put it back on, their mask time continues from where it left off (Ex: If they have 5 posts remaining of mask time, they use Bankai, it reduces to 2). It would add a bit more challenge to the race as well, knowing when to use their mask to gain the maximum advantage.
Important note: Kido Corps Captains have been shown not to wield a Zanpaktou (Atleast those we have seen). I like to think that it is because using a Zanpaktou requires more thought, and therefore weakens the Kido. As such, they chose to specialize in it. I think they should have full use of Kido and no Zanpaktou, personally, but that's just me. Agree.
Overall. I shall click the little agree botton.
p.s. I will probably be posting on most things the admins put up... It's what I do... So yeah... *Waves*
