How do YOU upgrade your troops?

Troop power levels

@Gryphonknight

In general, a 3* lvl 3 troop is better than a maxed 2* lvl 15 troop and a 4* lvl 1 troops is better than a 3* lvl 9 troop, so I keep three of every 3* and 4* troop for use with my 3 color teams since you don’t even have to level a 3* or 4* troop to have them become immediately useful, see above, but if you don’t have them, you can spend hundreds of summons trying to get them back, this is a lesson I learned with my duplicate Banes.

It will become a lot easier when next non-bug update rolls out ( Devs have promised the ability to favorite troops ).

Sets

3* lvl 01 and 3* lvl 10

For Epic tier completion bonus on challenge events, I currently have 3x full sets of 3* lvl 01 troops and 1x 3* lvl 10 of my favorite troops.

A full set of troop being one of each type so fifteen for 3* and ten for 4*.

Clarification:
Generally a 3* lvl 10 Troop is equal to, or slightly better than, a 4* lvl 1 troop.

So 3* lvl 10 troops are currently some of the most versatile troops in the game from a cost efficiency point of view.

4* lvl 01 and 4* lvl 17

Eventually I hope to have 3x full set of 4* lvl 01 troops and 1x full set of 4* lvl X troops.

I am considering leveling my 4* troops only to level 17 since that seems to be the half way point for the prime stat.

Example
If the prime stat is Defense, a 4* lvl 1 troop has a +16% Defense and a 4* lvl 30 troop has a +25% Defense. According to my records, a 4* lvl 17 should be +21% ( based on a lvl 13 being +20% ).

Methology

Instead of leveling my troops when I get new troops, I level my troops when I have enough for a full level.

Example:
I will hoard food and troops until I have enough troops to increase my blue 4* troop +1 level, then I will level it.

This way I can get a better troop, or change my mind about a favorite troop, and I am not stuck with an unused troop at 50% to the next level.
