No I'm not, why the fuck would he win? Rook Does NOT have low armor, yes UB has more natural armor, but the difference is so small and is ussually overcome by the Rook having so many chestpieces while the UB can go full hp but will lose on dmg and speed which arent very important for Rook.
Rook has the second lowest base armor rating in the game, 20 points higher than Erebus and tied with TB. Both, however, gain more armor per level than him. Also, the difference between UB's and Rook's base armor is more than 200.
Towers easily out dps ooze unless you got more than 50 armor mitigation and the Rook hasent prorperly positoned them. Most Dps from Rook does not come from his autoattack, so the ooze debuff isnt really that usefull.
Being a skill armor does not affect ooze, and by mid-game most ooze builds have stacked armor to the point where each tower shot does slightly over 100 damage.
Uhm Hammerslam is 1.5 secs,RR I is 1.5 secs. if he attacking you you can just RR than it takes around .35 secs for lag and reaction, than you hit with hammerslam. This means that he has .35 secs to get away, now it can be done if the Rook is a bit slow, but even if he runs away... he gets pounded by Rooks towers shoulders and AA. Rook has naturally more hp, slightly less armor, but he only needs a mana helm some potion and consumables and the rest can be pretty much armor or general stat boosters(unbreakable boots).
Their health will be more or less the same by mid-game, and those consumables and hammer slam can be interrupted by foul grasp, even with boulder roll.
No I'm just saying that no DG can kill a Rook in his castle without sieging the castle first. 1750 gold for vlemisch and a mana potion, thats a lot? Maybe a super hp stacked UB will be able to have more health, but I doubt it very much, since you are in possesion of the hp flag(if you any sort of brain). Now your gonna say I wont be able to build my castle at the hp flag, but that bollocks. Speed isnt needed, only for lategame, I just slowly creep my towers to eenemy base, and teleport around.
Hammerslam rank2 at level 10-11, at lvl 15 I have it maxed obviously. Now Rook isnt OP, he can be killed in his castle, but he can be attrioned down, run around or ganked since he is slow(but you can tele out) and his tower dont scale.
Not every map has a neutral hp flag.
So for the number: lvl10-12, I have hammerslam II or III and RookRoll I plus max towers shoulders and godstrenthg.
The Ub has 5.8 k hp, maxed ooze and some stats.
I have5.3 k plus hp flag.
The UB charges in and get pounded by my towers 500 hp lost, he tries to attack and I Rookroll my AA towers and shoulders do another 400 dmg. He begins to attack, I lose 280 hp every second while he loses 8* lets say 80 dmg plus AA and shoulder which do another 200 dps. If he tries to foulgrasp me I hammerslam him, if he evades I abort and get some hits in, if he does not he loses 900-1300 dm. Its pretty clear now no?
Hammer Slam's cast time is 1.5 seconds, there's no way UB won't be able to interrupt it. Those numbers are just plain wrong.
