Is Latios worth dumping dollar in for 100IV for future mega?
So all the lengendary in gen 3 except the Regis has the mega form ,
while most of the lengendary in gen 4, 5 and 7 don’t have mega. (especially those strong dragon from gen 4 and 5 )
Is it worth chasing the latios like we did for Kyogre and rayquaza?
Latios mega should be super tanky dragon with high attack while rayquaza mega still kinda a glass cannon
Answers
I think you may want to consider the two following possibilities first:
1. Niantic may/may not implement mega forms, and if they do, there's no telling how it will be done.
2. Mega evos don't happen til Gen 6, so you'd be investing in something we probably won't see for ~2 years.
Given that those two possibilities involve both chance and time, if you're considering chasing after a 100 Latios, you may also want to consider whether or not you'd find a use for one in the more immediate future.
Megas are so far into the future and may not even come to the game at all that you should not put heavy resources into preparing for them. Latios is going to be a great gym sweeper if you lack a DB/DC Dragonite, but I would not go nuts raiding it unless you have a great deal of disposable time and income.
