@Antman: Okay, I think I'm going to reword that section. In the meantime, here is a breakdown:
- You must have access to 14 heroes that have reached level 5+ (Both your owned heroes and free rotation heroes count toward this)
- Heroes that are under level 5 do not count toward this
- Heroes that are under level 5 cannot be selected in ranked drafts. (Meaning, if you have 15 heroes, but only 14 of them are level 5+, you can only select 14 of them
So basically no more needing rank 30 to play HL, but you must have 14 unique heroes all above level 5 in order to go into HL games. Gotta start leveling some useless heroes on my smurf so I can cover the 14

Also, bans coming to HL basically means Li-Ming is no longer playable there in like 90% of the games... Oh well. I like Falstad more lately. More fun.
