Forging a non-plus boss armor can be interesting if you're not far in the game but have strong friends. With the storyline and tournament quests combined, you can get enough gems to get the required boss armor material. The legendary armor will be good for beating the remaining areas.

Reviving the team usually is a very bad idea. Better refill the energy for 2 gems less and use other frieds. Or, if the boss becomes too strong, use the summoning stone. The summoned boss is very weak, gives 2 materials, and summoning costs only 11 gems for the current boss. IMHO, those are also the two best ways to spend gems. Later in the game it's to get the + armor, but the general concept remains.

Another good use can be to revive in guild wars, but it's only worth it if you're close to another rank.

And, as said, a 4th armory is a good idea as well. Upgrading it to lvl 3 isn't that useful imho, 10% less time (or 5% compared to lvl 2) doesn't really save you that much. With legendary armors (3 days), it usually just causes the armor to be finished in the middle of the night for me... Upgrading e.g. training fields could be more interesting, but there's no information if / how much faster money comes in. Otherwise it only would help if you don't collect that often.
