I am not quite sure, if this is the correct place for this question, but:
I have just caught a Latios and I am not sure, if it is worth keeping it or if I should soft reset and try again.
Hasty nature (-Def / +Speed)
IVs: 31 HP / 30-31 Attack / 8-10 Def / 31 Sp.A / 29-31 S.Def / 26-28 Speed
The only thing that bothers me about this Latios is its speed since I dont't know, whether these 3 to 5 missing IVs are relevant in terms of speed tiers or not. It might be noteworthy that this Latios was "caught" (or rather given to me) on Omega Ruby, whereas I can still catch another one in Alpha Sapphire with the Eon Ticket and that I could influence the latter's nature via a Synchronizer.
