Help Beating JMK and CAT

also depends on whether 3v3 or 5v5. I consistently win 5v5 (even against lvl 9 JMK DCs) using JML, JKL, HY, JKR and GAS. Focus down CAT after her dmg immunity is gone, then i go for gas, AT, JMK and finally GK. Want to get JML's ult off asap, but also heal with HY and JKR when possible. wait to use JKL's mass stun until after JMK's first ULT. 3v3 has been much more difficult for me since DCs came out. Was previously able to beat JMK, GK & CAT fairly easily with JML, JKL and HY, or Rey, JKR and Jolee. Those haven't been working as well since the JMK DCs came out
