Pretty tired of people still claiming ops are OP etc etc, the fact is, operative defense CDs are bad, shield probe absorbs literally one decent hitting ability if even, and evasion is only 3 - 4 seconds of ranged/melee defense and every class has an ability to use through that, for example, marauder though primarily melee has force scream and smash.
Sure, you may not be able to kill an operative because he can stealth and surgical probe under 30%, but when hes using surgical probe or stealthing his team isn't getting any spectacular heals, people argue that ops are OP just because of the scoreboard and how ops get higher overall heals, but thats only because of AOE heals to top off your health, in terms of single target sorceror is more useful because they have higher single target heals, hell look at the world record for highest single heal and you will see what i meant earlier when i said
sorc - least survivability - highest single target heals
op - mid
merc - heavy armor/hydraulic over-ride/25% shield/some interrupt immunity
world record for biggest single target heal
sorc - Anotei (Jar'kai Sword) (13597) http://i.imgur.com/auavhDK.jpg
operative - Braaxus-kun(The Bastion) (10688) http://i.imgur.com/7XeakrJ.jpg
merc - Physco(Jedi Covenant) (9326) http://i1180.photobucket.com/albums/...2-30-33-05.png
the fact is
sorc does least well under pressure - best single target heal
operative is in the middle (sure it can GET AWAY - but he ISNT doing BIG heals while running) - mid single target
mercenary can take the most pressure - lowest single target heal
