I do not agree. One thing that you don't consider is leveling difficulties. 5 pallys and that's a team you will play up to lvl 60 are so bad at leveling, that it's just horrible, starting from mana issues finishing that if you play with 5 mele, you need almost always follow/unfollow and even with broadcasting ( I play that on my own risk, it will take so much time) And talking about T10, I'm going for fresh server, so it's starts with just T7 and will be like that for at least 3 months.
In the end of a day with 3.0-3.1 4p+1dk is not a best option by far, because of hard leveling and not best endgame clearance.
