yea I think 7-3 in Raiden's favor. The MU is so frustrating for ermac. Nothing you do is fast enough because he can just teleport out of whatever pressure you are attempting to do. You cant zone him because he can teleport.
Essentially, Raiden dances around you and you just sit there and get impregnated
It is not 7-3. More like 6-4 for raiden.
You can not shoot fireballs because of teleport.
Superman beats tkp at any range. So only use tkp to punish things.
Raiden has even slower normals then you do. Play a solid neutral game and try to read when your opponent likes to teleport.
End combos in F4. This leaves raiden in front of you. He has a big hitbox, so you can take advantage of that.
You definitely need to approach carefully but when you have the life lead, he will need to come to you. At that time is when you pick him apart and beat his approach. Raiden has a hard time to regain the life lead, so you need to always work towards gaining the life lead and then holding it
