Its been said the limiting factor to your power in this game is the combat deck. You can switch between 10 decks readily and if you have every spot locked, you can have every magic spell, tactical glyph, and a weapon and armor skill available to use in a single fight. So a practiced individual can literally use nearly every combat skill in the game in a fight. If you use unlocked glyphs you could really have everything ready when you need it. Im also being told the cooldown on consumables resets if you swap deck, so you could continuously spam potions. EDIT: im told this is incorrect I then thought maybe your gear limits you but people can switch weapons very quickly, and even if you switch armor its only a few seconds. Is there anybody that is using 3 or 4 decks in a single fight?
