Would you transfer your low IV legendaries?

I rather have a pidgey that I can evolve for XP than a Pokemon that is non-legacy for his looks. So yes, I only keep 3 of each and erase the others from existence.

I will dump 'spares' in the next double candy event

Probably have transferred 40+ already

I transferred several during the double candy event and will probably transfer a few at the end of the month. I only need 1 of each.

I am afraid the RNG gods will hate me, if I transfer a legendary, but I probably won't keep more than six of any species, eventually

Too bad they can't be transferred to those of us who can't get them....

Yeah. That's how PoGo works.
You need candy to power up. You get candy catching and transfering to the professor

After I got a few above the 82% appraisal mark, I culled the rest under that cutoff and immediately grind up any new ones under that mark. Harder to transfer the 82%-89% range, especially when they have the moveset that I want and my 91+% doesn't.

Just have a think if you have absolutely no alternative to transfer (e.g. your Seaking or Murkrows), then go ahead.

IF/when these Legendary are gone...and you cant get them anymore (or not for a while till they return). Im not sure if I would be happy with a decision to transfer a bunch of them.

unless maybe, I had over 10 of each.

If trading does become a thing...im sure there would be tons of players who would trade anything for a Legendary Bird, regardless of its IV's. There WILL be people who have not caught a single Legendary, so it will be like gold to them.

I would happy swap someone a lower IV spare Moltres for a deccent IV Larvitar/Tyranitar for example....and if they already have good Tyranitars and dont exactly value it all that much...I bet the trade on their end would be more than worth it too, so everyone would be happy with the result.

Anyway, basically for the sake of a few bag slots that would otherwise be being taken up with something generic...I think a pokemon that is 'Legendary' can justify being kept.

I think having over 5, then I would begin to consider it.
