Meiling has very nice stats, she's all-around great except she's slow as molasses with skill active (of course, just time skill so you get benefit for most/all of the long duration)

BTW, any opinions on the new tanks? I got both and:
O-1 Mayumi: Skill: +55% armor, 60% Attack Speed 20 sec. Once per battle. Passive: Multi-turret "Uses multiple guns in combat"

Ho-Rii 2 Chie: Rapidfire: +100% Attack Speed and 25% damage for 5 seconds.

Chie seems average, I don't use any tanks with Rapidfire, does it have short CD? Because otherwise seems pretty meh.
Mayumi's skill doesn't add Evasion, just armor and attack speed and is once per battle. On the other hand the passive sounds interesting
