First and foremost i'm excited for the strictly functionnal changes to the UI and the targetting mechanics. Everything that will change what happens between the human and the machine. Appreciate that a lot.
There's lots to be thankful for. I don't think they could put off the physical level removal part to 1.19a though. It's like the main dish. Travel has already been addressed in part with the "set home" function. Thank you very much. However, airships to the main cities, if only that would certainly be very appreciated. (Wait where did i read that).
Personnally i'm in the 20-40 range now so rebalancing the character growth (aimed for disciple of the land) would impact me more but your 1 year veterans would probably like an enounter more.
Tutorials are major for your new players and i do belive i've made a thread about that somewhere. But with the changes to the UI you may not actually need them. An online webpage could address that possibly.
In conclusion i would suggest that you set yourself realistic main objectives and complete to the deadline with smaller easier changes.
