Yeah Doom does seem a bit awkward for first time players, but once you get used to his normals and their capabilities (range, start-up time, priorities, etc) then he can be fun to use. Doom has A LOT in his arsenal. IMO, it’s just the slow start-up & long recovery time of his certain moves that prevents him being god-tier.
I would run those characters in this order: IM(AA)/S/D, S/D/T(Proj) and S/C(AA)/D
For IM/S/D you want to use IM to build meter for Strider. Team disadvantage is getting stomped out by Sent.
For S/D/T you can call Tron and teleport -> major damage. Team disadvantage is if Strider dies, then Doom has to fend for himself with a limited range assist.
For S/Cable(AA)/D you now have a legitimate AA to knock ppl out of the air. Just don’t abuse Cable AA of he will get punished, especially against Sent/CC. Team disadvantage is Strider uses up all the meters that Cable needs to make him a threat. However, Cable can still fair well with Doom AA without meter.
Try them all out and see which suits you the best. Personally I would run IM/S/D because I like IM.:bgrin:
