You have to get a read to make the most of a 3-second-charge trait which persists through hits and pushblock and makes literally everything safe? As in if you ended a combo with shackles you could probably get 2/3 of that trait back on the spot? What about all of the characters who have to wait much longer periods? (Flash, for example). What about all the characters with similar problems and without projectiles? What about characters who have worse kits altogether AND get worse drawbacks than simply not having it?
Why should sinestro, a solid character whose trait simply accents it to the point of stupidity, not lose his trait when characters like Bane lose it and get shafted for not having it? Or characters like Batman whom, without their trait, are worse overall than sinestro and lose it upon being hit and pushblocked? Or characters like Flash whom lack projectiles altogether and can't use his trait until its full with no means to hasten the process and lose it with every single thing that comes by?
Honestly I'll be happy to trade you traits if you want. I'll be more than happy to have something that makes literally everything in my already solid kit even safer over something that I lose pretty much for free if I get hit even once and doesn't even work properly against some of the cast. :/ You having to charge it doesn't make it anything special or super difficult when you have the means to charge it in your free time and it takes no time to charge as it is.
