Merc's are definitely OP.
I have a lv188 Merc (borrowed Echo from my lv200 char) and it got 12:xx as its time.
It has less funding than my other characters (1 item Rare and a few Epics), yet slaughters my other character times.
Also interested in whether or not there are tips for Dojo as a Merc because all I did was IR, occasionally Spikes Royale for the later bosses to dodge + hit (earlier bosses I find the extra IR's kill already so no point in getting that extra PDR).
I've heard of hugging Manon/Griff but that failed for me. I've also tried spamming invincibility frames but I kill much slower than IR this way. If I keep out of their attack range, a lot of my IR's seem to miss, so for now I'm just gambling that they miss me with their dispell.
