So while I absolutely love playing a shugenja I will be one of the first to admit they can be severely overpowered, specifically in versatility, there is no way a courtier or bushi can hope to be relevant to as many situations as a well-rounded shugenja .
This is the point a lot of people have been making. And it is true. They are very powerful, and spells are very powerful.
The problem I have with it is this. Why does everything need to be around the same power level? There is an assumption that this is how it should be, and I think it is a thought process/mentality that comes from things like video games and card games. RPG's are very much separate from these and shouldn't necessarily follow the same rules of balance.
To me it would make absolutely no sense at all, if Shugenja were on the same power level of bushi. They can control the elements, alter reality etc. They are not wizards per se but they can call on favours from the spirits that make up the world of Rokugan. How can, and why should, a bushi be at the same power level as a character that can do that?
I understand there are people who get different things out of RPG's. And I have all different kinds of gamer in my group. We pretty much have always acknowledged that shugs are really powerful. All it meant is that you have to find ways around them. It's hard to face a fire/earth shug in combat, so you just need to find a way around him. Alter his scrolls, poison him, call him out in a duel, there are hundreds of ways around it!
I've also never played in a party that had more than 2 shugs (and 2 was a rarity), people usually play what they like in an rpg rather than what's OP (although we all know THAT guy who power games!
).
So yeah. Imo, it comes down to your expectation. If your expectation is that all "classes" should be on par then I understand the position. I just think that is an assumption some people have, and a view they have on the game, which they are perfectly entitled to. I however don't agree with that assumption!
Nonetheless, nice post!
