AST card system idea

[IanFrench]

I feel this might be too OP.

AST's main problems are
1. CU&CO are too weak. Extremely unacceptable comparing to its counterpart Sacred Soil/Asylum/Assize.
2. new card system is a trash (keep you busy for nothing), 15 secs card duration is like a joke to AST players, and divination is on 180s CD for 15s buff...
3. Mana management, both whm and sch have their unique ability for mana generation other than Lucid Dreaming, AST used to have Ewer (RNG, but can be extended if necessary). In ShB this has been removed without any compensation.

My suggestion:

1. Reverse the changes to CU and double the current CO potency,
2. Cards need to last at least 30s long, and some other changes need to be done as well, especially Sleeve Draw (immediately give 3 seals and restore divination CD maybe, but feels too OP again)
3. Give CO mana regeneration ability at least 10% since it has 120s CD (Scholar has 10% mp return on 60s CD, Whm has 5%mp return on 45s CD), that way AST still have the weakest MP return among the three healers which is exactly what the Dev desired (ironic)!!
