Haven't touched HS since and will never again unless HS changes its price tag. Both as F2P or paying player, in LoR you get sooooo much more for your time/money. And the meta is still really diverse. There are like 5-6 deck archetypes that I can think of from the top of my head that are T1 and there isn't one that clearly dominates all the others (Draven/Jinx aggro, Spider aggro, Wraiths/Hecarim midrange, Frost midrange, Elusive cheese, Ezreal Control/OTK) and I think with Riots announced monthly micro-balancing, it will remain that way.
Riot has also announced that they will continue to balance stuff to keep every champion is present in at least one competitive deck archetype and every region part of at least one T1 deck.
