reread the fight between konan and tobi..
tobi can't atack if he's not in his physical form..
--> therefore no fightdevelopment..
also when he change into his physical form.. he has to wait a little before he goes into his "you cant hit me"-mode
konan nearly defeated tobi.. but he used izanagi (chapter 510)
his eyes wasn't shut because he is posseses senju's dna.. --> complete form of izanagi (also explained in chapter 510)
so for a fight he has to be in his physical form.. and we know NOTHING about his atacks..
also when he was meeting with the 5 kages.. he admitted that he IS currently weak! (also explains why he wasn't involved in a real fight)
now that he possesses the rinnegan he is different....
but because u said "pre rinnegan" we can't expect much from him..
