There should be an option on the teambuilder that allows the increased stats of items such as Choice items or Assault Vest to be displayed. For example, if you give a Choice Scarf to max speed Timid Hydreigon, instead of 324 speed it would display 486. Also the teambuilder should show stats of mega pokemon forms. I believe these additions would benefit people looking to build more complicated EV spreads than 252/252/4 sets.
I think you can see the stats of the megas if you do a search for one and select it. It's not very convenient though, so making it easier would be nice!
I thought it was a new person who asked this. Then I saw it was Kyrk. XD Anyways, yeah I agree with this idea also, I know Pokemon Showdown displays the Mega Pokemon Stats in the TeamBuilder, but enabling that into PO's TeamBuilder as well as the increased stats of boosting items etc. would be a very nice touch.
This would be quite nice, if inessential. Usually I just bring up my calculator where I need it but having this be easier would be great. It'd be especially good for megas, too.
for megas just find the Mega Pokemon in the advanced search (Click Pokemon Icon > Click Pokemon Sprite > Input Valid Search Criteria). Just make sure you don't have that Pokemon's base form in your party, or else it won't work. I don't think stat changes / abilities / anything else should be included in teambuilders. For example, if you're going to put in something for Mega Medicham, there's always a (sometimes obscure) way of eliminating such a factor (for abilities, there's Gastro Acid / Worry Seed, stat changes = Unaware, Haze, Clear Smog). Unless, of course the option to display these stat changes is optional. Then I'm all for it.
