Pros: Damn good heals. I have 306 gear, but no set bonus or augments and my heal numbers are almost as high as my merc. And I've done under 20 matches with this character. Stealth is a bonus and the two forward rolls are handy.
Cons: Mobility. Very few heals can be cast while moving. DCDs are a downside too. I miss my reflect shield, the op shield seems almost useless same with the dodge. And the sleep dart I can't seem to use in pvp?? This might actually be a bug but I'm not sure. And there's no pushbacks. Like don't the majority of the classes have pushbacks?
Overall: The agent story was AMAZING. Loved it. Loved every second of playing it, well except for Scorpio. Fuck Scorpio she's so annoying. Op heals are just downright fun to play. Kolto waves makes a fun sound, keeping up probes is p easy and does a good chunk of the healing for you, burst healing isn't great but it's not as bad as some people make it out to be. Also, in a round of 4v4, it ended up being my op and a tank winning against 3 DPS players. It was amazing. And the next round I died within seconds because I got tunneled HARD. And the DCDs for ops suck. I am loving end game ops heals and I can also work on more objectives since I have a stealth ability.
