When you use characters that are above the level limit for a particular adventure or quest, your character level is set to that limit and you loose power tokens and hit points accordingly, but all your inventory slots remain open. For low level adventures, that means you need to fill up a whole 36 cards deck with non token items instead of just 10 to 20 making your deck vastly more unreliable. This difference is especially important for "you only have 1 hp" quests. It's pretty annoying that an actual low level party can be so much better at doing these (can afford to only equip epics/rares with no dead cards in deck) than a higher level one. The inventory slots should disappear along your levels.
I'm sure there are technical problems with removing inventory slots (since obviously it should). But for me, its not a big problems. You get a full inventory by the time you reach lvl 6 (and your first token at lvl 7). Fighting a module 2 lvl above your character get a full lvl of experience so it's very easy to lvl up before doing the proper quest. (The most you will ever need is lvl 5, which requires fighting only 4 module). Hiring new lvl 1 char is only 10 gold each. Though atm, the "Only 1 HP challange" is currently bugged and you can play it with full HP
I have found in some of the level 2-4 challenge modes you have a huge advantage with the monster deck if you stack it in one direction like a wizard with as many penetrating zaps as possible. Since these levels were designed with less equipment slots, they should be reduced for the challanges, maybe?
I'm wondering if there are any plans to address this inconsistency. I started a couple of new character today and had a bit of fun with the low level quests. I'm intending to level up their new characters, but it would be nice if I could again play with reduced equipment slots without having to buy new characters. If the equipment slot inconsistency is not going to be fixed, then maybe I'll try to delay the leveling of my new characters by doing quests rather than missions.
Working as intended, according to Jon: http://www.cardhunter.com/forum/thr...ts-you-keep-higher-level-slots.759/#post-9486
