Yeah camping could definitely become a thing if there is not enough incentive to move up and improve your deck.
Still I see it as a step in the right direction. Bringing back level caps already solves part of the problem.
I also think it is very hard to design the perfect system when things are constant chancing not only in the game but also gamers. Sometimes we just need to try something, see how players behave, and improve it afterwards.
