Given only having limited storage, especially with Gen 2, I'm wondering if there's a reason to hold onto IV pokemon that have bad movesets if I have other pokemon with not as high IVs (90% and above), but with Grade A/B movesets. Do you think there will be a case where they will become shinies or that there may be a chance to change movesets down the line?
Two features that have a very high chance to make their way to PoGo is the option to select movesets (maybe a reroll) and also breeding. Two features that could benefit you if you save those high IV mons.
There's also the possibility of a bad moveset becoming a better moveset with a rebalance. Like we saw during the last rebalances.
Just one caveat... in breeding, what matters is the number of perfect IV's, meaing that a pokemon with 15/15/5 IV's would be more valuable than one with 14/14/14, because when you breed the first one, you get the chance of 2 perfect IV's, where for the second one, none of the inhereted IV's would be perfect. This is, if it works like in the main game series.
Given the fact that rigth now all eggs garantee 10/10/10, I think it's unlikely that IV breeding becomes a thing
I doubt any Pokemon will become shiny, and I see little reason why Niantic would implement moveset re-rolling. I think the best hope for high IV+bad moveset Mons is a rebalance buffing whatever sub-optimal moves they possess (e.g. Gengar and Clefable's best offensive movesets right now were previously suboptimal). Also keep track of Mons that will gain evolutions in future generations - I would keep your highest IVs of those Mons.
Depends on the Mon. I wouldn't recommend getting rid of High-IV Blissey, Snorlax, Dragonite, Gyarados, Rhydon, or Tyranatar regardless of moveset. You also should consider use. There may be a C moveset that fills a specific niche as an attacker in you local gym situation. If a mon has 95+% IV you may also want to keep in in case the moves are rebalanced again in the future or the becomes a way to re-roll movesets.
With those considerations, moveset is generally more important that a slightly better IV.
Some people are suggesting breeding as a reason, which could be valid... but only if it has perfect values in one or more of the stats, at least if it works like in the main game series, because IV's are inhereted directly, so for breeding it would be more valuable a pokemon with 15/15/5 than one with 14/14/14
As for moves re-roll or TM's that's a posibility, I'd keep the high IV ones (you pic the cut value), in case they can be useful for breeding or a mechanic that allows for control over movesets is introduced.
With a storage cap of 1000....i think theres always room, and relevance in holding onto any good IV Pokemon...especially ones of rarity/higher evolutions that costs rare candy.
Obviously with the main reason and hope...that eventually we get move rerolling.
But also just because the game can change and moves can be completely rebalanced so who knows what may be good eventually that is currently just meh.
