I've personally aspired to be both unbeatable in 1v1 and the biggest attribute to my team I can be during team matches.
In a world where COR has a decent shot to take out BLU's and RDM's, you find that people like to make bold claims against a system they have little to no understanding in.
DRG isn't strictly a DD it can heal itself easily and sub mage to just have a very powerful edge.
Everyone who isn't total crap on a martial job is going to run /sch to get magicla utility and be immune to sleep while HP above 50%, DNC/SCH with a strong evasion build can dispel pressure, aspir, drain, and cure themselves nearly to outlast any job in the game.
Enfeebles Oh God What do I do:
They already have this, its called resistance gear to remove enfeebling strength, and diminishing returns on enfeebles. This gear is very potent and it is very easy to gear to be nearly immune to any job casting the enfeeble you target, with only a RDM having a chance and thats if they are gearing specifically to land, which opens them up to physical/magical damage and ruins their pdt/mdt options.
WAR and MNK have it rough, but MNK at least has the option of mitigating nearly all physical damage on most jobs, and the ability to run resist sets with obscene damage (Spharai etc.) and get magical utility to wipe stoneskin, erase itself, and put on the dispel pressure.
There's ensilence weapons that can be obtained that are potent.
WAR - I have some builds using /sch and mp merits and the natural retarded DPS and DA chance of the job, but I'd have to tool with it more.
I destroy RDM's on my DRK all the time and its not because I can enfeeble better, or cast faster than them.
