Slightly different than my topic of elite specs. But I think a good more general topic for the new expansion.
Personally, I think for me its just the new land itself. I love desert environments (it has other biomes too though), and it sounds like the zones will be huge since mounts are involved. GW2 zones already felt nicely sized though to me, especially with how packed they were full of stuff. That is the one thing that worries me about the new lands, if its going to feel empty or the same as HoT zones...stuff all over the place.
The 2nd thing I actually am excited the most about is...the mounts sound actually like some of the best mounts (mechanic wise) in an MMO (at least out of the ones I've personally played). I haven't seen an MMO where different mounts actually have unique mechanics (besides flying, which doesn't actually count). They seem awesome. Very excited to get my hands on one.
What about you guys, what are you most excited for that has been revealed thus far in Path of Fire?
