For comparison with current live troop xp values, getting a troop to lvl 30 requires
63,800 xp, which would be
1595 1* troops fed -or-
709 2* troops fed -or-
319 3* troops fed
Assuming my math is right, and the math of @2puttshaqur is right, that means it will take less feeders to get from a new 4* troop to maxed 5* troop than it currently takes to get to lvl 30 on a 4* troop
Edit - I don’t know if my my xp values are correct. The chart I’m looking at says 52325 xp for lvl 26, 63800xp for lvl 29
Edit 2 - the valued stated seem to be for lvl 27 and lvl 30, actually… But still have a different value than 2putt for lvl 26 at 48750. Instead of doing math for lvl 29 using correct xp values, changed it to reflect lvl 30
