So, what's the importance of IVs?

I've adopted a new way of playing by saving my stardust for high IV + preferable moveset attackers/Pokemon in general and depending on evolving high level wild pokemon I catch to fill niches like this. So for example, I don't waste all the dust pumping up a hatched one or lower than level 27 and I then use the dust I saved towards a high IV Machamp/T-Tar/etc. The key is using TM's and finding wild Pokemon for me.

Interesting question . . . in my view IVs still matter, but less than before.

Attackers do not really need to be powered-up beyond level 30 due to the decreased gain in CP thereafter.

Defenders now don't need to be powered up above 3000 CP (lose motivation much faster).

So, for defenders with a max CP lower than 3000, good IVs matter to get the highest CP possible. For defenders with a max CP above 3000, good IVs matter to save stardust in getting to 2970-3000.

For attackers, good IVs are useful for getting higher CP at level 30, but this is not so important.

Good movesets are what is required now - for both defending and attacking and are much more important than good IVs.

I think now game have change to focus on attacking, to attack gym, nothing to worry much but for attacking raid bosses, with time limit, highest effective mons as well as highest CP and IV in your level should be considerred.

I don't evolve or power up anything less than 90+IV now. High IV is just as important as before and will -- I imagine -- always be.

You really notice when your Pokemon is missing stats once you have some perfect, or 91+ pokemon. How can people say ivs don't matter? You're either trash, or a troll. Have patience and do it riight. It's better to have 2 of a perfect or close to perfect Pokemon than to have 6 trash ones.
