I have never seen an erebus capable of beating occ on crucible. On fortress, you could, but only because erebus's massive number of nightwalkers can take down forts so easily that even occs massive splash cant stop them in time. With incompetent erebus's like prussian havok and flashrusher, they can't even beat me on fort, but im guessing a real erebus could. theres only 3 forts after all. But IMO oc is the king of the crucible. The single lane of one portal worth of creeps simply cant get past him, the only way to win is to be destroying him, and with centre jumping, and chain lightening, the flag and experience domination is very advantageous, and oc's ability to destroy the enemies minions while keeping his own, makes him difficult to stop. I'm pretty sure the only dgs that beast oc on cat are beast and rook, beast already explain and rook because not even oc can stop the tower pushing into your base, 1v1 rooks towers are so hard to stop, ocs power is in his minions, and the towers take those out pretty easily. as for prison, oc can beat rook on prison, there are no lanes, towers are less effective, however this is not GUARANTEED, i wouldn't say either oc or rook is unstoppable in this situation. Needs more testing. As for any map, erebus simply cant match up to oculus. erebus's massive lack of splash damage and ocs massive splash damage, match up to erebus ending up without minions for the majority of the fight, a well played erebus cant actually be Killed, but pushed fairly easily. This makes winning on crucible very easy, but more difficult on other maps. For example on prison oc will win, but the key to victory is to NOT get into any battles until you have the advantage, dying early can finish you. On prison, ocs ability to farm BOTH sides of creeps, will make him outlvl erebus, and once oc gets to lvl 16, and exploding BALLZ. Erebus can only stand up to that if you've let him kill you a few times, or dominate the game in some other way, which will only happen if you let him. As for queen, I haven't played a pro queen 1v1, but I have played some queens, and i would assume that although queens good splash damage would help her with ocs minions, its still less damage overall, and less splash than oc, if not dominated before lvl 16, i would predict with the exploding ballz, the queen would be DONE, as she gets weaker late game.
