Looking for the 'right' realm

I'm an old player here, though I haven't been around for quite some time. I actually haven't played here much since it was Molten - though I am thinking of coming back and prefer on playing Lord.

BUT

thats where this question comes in... Im not sure if this realm is right for me. I have read a bit about it and a lot of people are complaining about try hard blah blah blah which i don't think i would mind too much, however, i don't have as much time to play as i used to. Does the 'hardcore' style of this realm require players to be on for 5 hour spans daily to get anything done? or could a more causal player still make some good progress with ~15 hours per week?
