>>45816210Based bionicleposter, takanuva is indeed cool. Personally I like metru builds with it as opposed to the gigachad late-g1 takanuva but that's just me.
As for the actual question, no.
Maximizing HP EVs on a mon you're going to dynamax won't do much bulk wise and losing attack means your broken ass nuke is not going to kill something, and therefore you won't be able to easily snowball your buffs and abuse those 3 turns you have to break shit.
Now, if the mon in question is slow already (think Glastrier), and you'd invest in HP no matter what, then the dynamax 2x HP is just the icing on a disgustingly sweet cake.
Basically, investing in HP just to get more hp when dynamaxed is a trap and doesn't work.
You only invest in HP on mons usually not suited for being bulky, so to speak, if you want it to survive a specific move from a specific mon (think like the 8 def EVs on mega gardevoir to make sure specs latios doesn't 2HKO you with psyshock).
