Question: Are you using relics and adrenals?
I can pop my crit relic and my power adrenal at the same time and get a 5-6k heal no problem. (Last night I got a 5900 crit in case you were wondering if this was post patch or not.) That's like 2 medals right there in a single fight. If I have time left over, I use one of my higher damage attacks and get a 2.5k damage medal. Then I pick a target that's about to die and auto-attack it, there's another medal for killing blow. Hell, cast an aoe heal in a big fight, you get your 10 enemies dead thing right then or soon after. All of this being done whlie I heal my group.
I just don't understand how people are complaining about getting so few medals medals when it is easier now than it ever ever was.
Work smarter, not harder.
