Was trying to snag ML Aramintha through mystic summons, got ML Dingo and Yufine instead. Pumped as I really need a buff stripper for guild wars
Was just about to come post this exact thing. I'd been saving my mystic coins, had like 500, got Yufine and then ML dingo back to back. Pretty stoked. Yufine is someone I've always wanted, she's got such a great kit--armor debuff and dispel and self buffs, pretty amazing for PvE and PvP.
Edit: Hah, daily pull before going into work gave Charlotte too too. Damn, crazy morning. Guess Ludwig is no longer my only free 5 star

.
But ML Dingo, Damn, he's actually pretty powerful. His S3 is ridiculous, it buffs him AND his target with invincibility and attack up. It works perfectly for a new team I'm building to try and break out of Challenger in Arena (Since I think we're going to see a lot of immunity sets soon). Going to use Dingo/Ludwig for a super cleave team. Ludwig has the highest base attack in the game, so going to toss an attack/crit set on him, and go for broke, as high as I can get him. Then use Dingo to attack up/Invincibility him, which gives his S3 50 Armor Pen. Should be pretty nasty, hopefully.
Dingo though, his attack scalar is 1.5 for the single and 1.3 for the AE, and the AE procs the S1 on crit. That's pretty obscene in terms of damage, most S1's are .9 to 1 and AE's usually don't get much higher than 1 for S2s.
