What about VIP Level?
Somehow I don't think you actually took some time in SH...
You're right about some points, others are complete nonsense.
Leveling takes its time atm, but they're already working on better exp rates for normal mobs, aswell as Dungeon ones. And if you farm Dungeons for the Dragons inside, you won't have a problem with your level. Only quests and PEs aren't enough, you have to do some more here.
As for marketplace prices, I don't think you've actually seen how the marketplace developed over the last few months. The progress is slow, but steady. There are new things in the marketplace and yes, at different prices than in DP. The Insignia marketplace is worked on aswell and more options should arrive soon.
Incubators always were and are reason for some arguements. With unlimited access to them, it'll end up like in DP, with 75-100 incubators on a 100*100 plot. Limited access just slows the progress and keeps people away from getting a lv100 Dragon in 10 days...
I don't know if selling them for Diamonds at first (and later for Insignias) is the right step or if it'll backfire more than it already did, but limiting incubators are (in my opinion) a great factor for SH.
Since you mentioned dragon training, the only thing that became harder is getting a Dragon to lv100. Raising Ones Dragon Partner to 100% instead got way easier with all the marketplace Dragons you get for free. Training and skills still take the same time as in DP.
Most of all, one think you seem to be forgetting is: Savage Hunt isn't the same as Dragon's Prophet. It needs to go a different way, otherwise it'll end up as dead as DP...
