I don't see why people complain about pro's / paras. 90% of you will just complain because chances are you will never have one or you've seen them unbalanced on another server (again most likely the enemy got it...) Heck if they are not ingame, remove clear, tele rings & revival rings. all unfair boosts if you want to be real picky.
People using the 'oh they make PVP impossible' is just an excuse. You are foolish to 1vs1 a warrior with a para if you are unable no keep away You wouldn't fight a lvl 44 warrior on a level 20.. People act asif they are forced to fight people with these items. Pick your times! Tatics are needed, not knuckle heads. In SW etc.. and guild wars people just need to focus on the person with the para / pro. As for boss sololing etc.. It hardly makes a massive difference.. soloing costs more pots & dura. Not like obtaining a para allows a level 38 warrior to solo EM...
Pro's could do with fine tweeking as they are a definite bonus to higher level with the larger mana pool they have.

Although Sam has said no to being ingame ideas for other people could be:
Para has dura 10/10. Every 50 sucessfull Para's it looses 1 dura (500 at best) also it looses dura at normal pace - This would in theory.. prevent people from using in wars etc.. as they are wasting a valuable asset.
Pro again dura 10/10. Every time mana hits 0 a dura is lost also using 1.5x MP for HP would be decent too..
