I'm all in favour of 1.4, as there will be a greater variety of intelligent decks (once the wheat and chaff have been sorted) and potential for themed quests sounds great. I would like to be able to win upgraded non rare cards by fighting strong enemies as I think there's more sense of achievement than spending money to upgrade stuff. E.g. for level 60+ish decks make all the spins give upgraded cards, not just the special spin like it was in the arena.
I would however be dubious as to only being able to change your deck in a palace, as I can see myself spending a lot of time traveling back and forth between the higher level areas at the edge of the map and the palace just so I can adjust pillars/cards and test them at the appropriate level. If you wanted to stop someone using a specific deck to beat a mob, then don't have a mob of the same enemy - make the opponents in the map area you occupy reset after a battle or have a greater variety of enemies within one map tile so you can't easily fight the same enemy twice in succession. If you still insist on only changing your deck in a palace, at least include some sort of fast travel or similar.
Zanz: On a separate note I've noticed there are a few bugs in the bestiary/trainer it would be nice if you could fix.
1) The mark in the bestiary is bugged so that multiple marks play as single marks when testing decks pre submission, I think others have already pointed this one out
2) Triple dexterity is bugged in that it works when testing in the bestiary but when playing it in the trainer it uses single draw with a deck that's three times the size of the original deck, which hurts even more than if it simply didn't work (see "Ninja" deck for an example).
It would be great if you could fix both of these as its quite difficult to gauge atm how a deck is actually going to perform once its submitted, thank you.
