6.60 and most of the succeeding versions that reflect 6.60 will bring with it some implications that will affect pub and leagues quite differently.
For pub, the greatest implication is a heavy tilt towards heroes of DPS potential. Remakes of Razor, Troll Warlord and Sniper, the most popular pub heroes; buffs on several others like Spiritbreaker, Phantom Assassin, Ursa Warrior and Windrunner; and important item remakes (Manta Style, Diffusal Blade, Aghanim) that have indirectly buffed heroes like Naga Siren, Phantom Lancer, Riki, Nightstalker and Chaos Knight, this version’s DPS assassins pack a heavy punch to annihilate all that defy them. Furthermore with the presence of Quelling Blade, most of the above heroes may scale their peak much faster. Sheer and brutal devastation has never been easier.
Furthermore, the presence of some defensive items that protect against spell damage, like Khadgar’s Pipe of Insight, can be easily interpreted by pubbies as a sign of the frog’s disapproval of spells. Granted, this may not be the case, but what matters a lot in Dota is perception.
In leagues, the end result may turn out to be different from what the frog desires - more DPS participation. In fact leaguers may very well ignore the signs and continue on the path of spell devastation as was common in 6.59. However, this time the attention will probably be more on spells that can deal % HP instead of a fixed amount. Ironically version 6.60 may also be termed The Tauren Chieftain’s Map, because his aura that can remove base spell resistance and the ultimate that removes %HP will surely feature heavily, if nothing much is done to change his skills.
Thus I expect that in addition to TC, some old 6.59 powerhouses like Enigma, Necrolyte and Undying will probably take on this map just as easily. Expect much of the situation in the house to be pretty much the same - you won’t be seeing the trio (plus TC) so much like in 6.59 (ban ban ban). Along the lines of %HP removal, leaguers might also throw in heroes that can play along and zap dying souls who managed to escape the pangs of mortality. Thus Zeus, the longest reigning God of leaguers will be comfortably entrenched in his position, as will heroes that have the same potential (who will they be?). Heroes that depend a little too much on spell damage, like Tinker (think BKB that cannot be rearmed), Tormented Soul, Queen of Pain and so on will probably not make it, unless room is made whereby they can take advantage of the situation described above.
Another less noticed tell-tale sign is the displacement combo as I related in the Batrider post. This group of heroes - Pudge, Vengeful, Batrider, Bloodseeker, Keeper of the Light, Omniknight - could also become popular (and rightly so), with buffs and the addition of the Force Staff.
In summary, I’m not very sure if the changes of 6.60 and the following versions will produce results that the frog wants. I hope it does, because change is embraced not forced.
