Look, I don't know if there is a mod for this or not, but there damn well needs to be. Especially since PO seems to have upped how damn often crits happen. Every match there will at LEAST be 3 or 4 crits that just end up completely screwing one person in the battle or the other. Sure, there are moves and abilities built around having hi-crit ratios and I'm all for those, but when you just want to have a match without horseshit crits just making the battle completely One-sided. This Clause could have so many great uses, from the Random "Find Battle" to Tournaments. I know I'm not the only person who bitches about crits, and I won't be the last, but think about how much people would shut up if this was implemented.
Yes crits are annoying but really that's just part of the game. Also they aren't so common where there is 3 to 4 a game. That is kind of a worse case scenario. And if you are wanting to ban crits based on what you said you might as well shoot to have moves with a chance to burn, paralyze, freeze, etc. banned too. The point is while it is annoying theres no reason to ban it. It is without a doubt part of the game and they are not usually as common as you say.
While true, the fact is even if it were a mod being optional and thus not a forced thing it would be nice to have. Like all the clauses you can turn them on or off if it so pleases you, I'm just suggesting something that will in the end cause less whining and bitching
This is not really modificable by changing the database alone, but rather a source change. However, this is very easy change in the source code and I can find you what to change if you interested in running a no-crit -server. Just remember, there is a lot more hax than just crits in the pokemon game.
I think the reason people feel there are more crits in PO compared to the games is because in the games your pokemon are usually a higher level and therefore faster then the pokemon you face and when you 1hko everything you are not going to see many crits and the ones that you do see will feel more insignificant.
