>>41417905>Is this a new mechanic they added now or something?It's actually been in the game since gen 1. In gen 1/2, they worked a bit differently, but the principle was pretty similar.
>Having EXP share off means that you get less EXP>I don't understand.Let me repeat my example.
Say you have a party of 6 pokemon, all at the same level. You beat an opponent that gives you 500 EXP. Without EXP share, the EXP is shared evenly between party members - so if you only fought with 1 pokemon, you get 500 EXP on that pokemon. If you fought with 5 pokemon, you get 100 EXP on each of those 5.
With EXP share, every pokemon that took part gets 500 EXP, and every pokemon that didn't take part gets 250 EXP. This means that, at absolute minimum, 1250 EXP has been given to you for free.
Let's take this concept to a larger scale. Say you have 6 level 1 pokemon, each which level up at the same rate. With this team, you fight enough pokemon to get 200,000 EXP.
If you didn't have EXP share on, and you trained each pokemon evenly, you'd have 6 level 34 pokemon.
If you trained with EXP share on, even if you only fought with 1 pokemon, you'd have 1 level 59 pokemon, and 5 level 47 pokemon. Despite having never seen a single battle, your 5 other pokemon got to a higher level than they would have if they fought their share fair of fights without EXP share.
This makes levelling up quickly easier, but Pokemon is more than just levelling up quickly. SS's difficulty curve doesn't properly match the extra levels that EXP share gives you, meaning that you can, without really trying, accidentally overlevel for many boss fights. This is why people want to be able to turn it off in a casual run - so that they can get less EXP, and be at a more reasonable level for additional challenge.
