Progress halted

Continuing the discussion from Progress wall:

Agreement here. Made it to lvl 5 for all my champs and I can’t progress in explore I just keep dieing, only options are to win/lose in arena and wait those chests out. VIP doesn’t help much I would have thought more then the 25% chance to get a little bit more gold from chest or the 1-5 gems. Need an area to grind items which are the best way to level up your champs, gold rewards aren’t too bad but would be nice if I could afford to level up items more then once every 4 chests opened.
