Fixing Avatar's Favour would actually really push SMN in a very different and positiv direction:
- enlarge the radious form 10 feet to 25 feet so you dont have to send your avatar in if you dont want to (if you are buffing melees)
- remove the BP penalty
- make the favour autocap right at start instead building up for 3 min until your avatar dies... over and over and over again or you use a BP.
the buffs are very nice, they just are useless, because: 1. you need to build them up and 2. your avatar has to be in range of people (so possible in range of melees/mobs) which means your avatar will die fast, which means you have to build the favour up again....
It is one buff an avatar's favour offers vs I dont know how many buffs other jobs can hand out. I dont see any problem with the changes I suggested, it surely wouldnt break the job...
