Support Casting is way too difficult

I don't think this is correct. % guilds will affect the duration, but my understanding is success rate is based on wpa.

From WIKI

Spell Duration
Percent Guilds is the sole factor involved in spell duration. The higher the percent guilds, the longer a spell will last. This remains true until the maximum duration for that particular spell is reached.

Self Spells
For self spells, a higher percent guilds results in a greater:
Spell Duration
Chance of a Successful Cast

Offensive Spells
For offensive spells, a higher percent guilds results in a greater:
Spell Duration

So is a supporting spell a "self" or "offensive"?
