Sadly no such changes, personally my big problem is that if you try to do all quest you will have to go trough the same dungeon over and over and over again which gets really old, they've included a encounter off option which is a band aid fix but at least that'll help (I would have preferred a speed up 2x-4x).I'm so torn on that game. On one hand its lovely and I would love to play it again. On the other, they really really need to change the exp system since that kept me from beating the last boss. You get an ai/player controlled helper but you level up by collecting crystals, the ai won't collect crystals so it will always be much much lower level then you unless you manually control it to actually collect the damn things. I would really hope they would change that so exp just pooled or got shared or something.
As for exp, did the golem party member need exp or were they entirely dependent on what material you put in them? I remember mostly ditching NPC party member since they'd usually die within a second if fight starting later on.
