Changes to Awakening Gems
Awakening Gems are one of the most sought after items in the game, particularly 4* and 5* gems. And they are super super rare. The rarity is matched by the utility of these objects. Some game-changing champions absolutely must be awakened to be good, so it makes sense that they are sought after.
The one big downside to them is, if you use one on a champion, and then later duplicate that same champion, your awesome extremely valuable item immediately has its value retroactively changed to that of a +1 signature stone.. which is of course terrible. Very few things in this game are more frustrating than using a 4* or 5* awakening game on a champion and then duping them soon after.
I suggest changing awakening gems to work exactly the same as if you dupe a champion. In other words, if you use a 4* awakening gem on an unawakened champion, instead of getting a single signature level, awakening them, and getting nothing else... awaken that champion, get 20 signature levels, plus all the gold and ISO you would get from duping the same champion.
Then, later, if you dupe the same champion, you don't have to feel like you completely wasted something that was so difficult to obtain.
I don't see why not... awakening gems are so extremely rare it's not like players would suddenly be flooded with resources. It would just be a good change.
One caveat: keep the basic arena the same as it is now. If you get a champion in Basic Arena that you already have in your inventory, it awakens them and you get one dupe level, nothing else. It's still frustrating if you then go on to duplicate the same champion soon thereafter... but... you also get 5* shards from Basic Arena, so it's not a total loss, AND... Basic Arena really SHOULD be for players who are relatively new and still building up their roster. Not for people looking for ISO and dupe levels. So it should stay the same. Just change the gems.
