Should I get Pathfinder?

[Leon]

NO.

Pathfinder does not fix balance problems. Fighters still have to take out their backup ranged weapon when flyers come out. Tier 1 is still very much tier 1. Heck, the only real difference is a good boost to the core paladin, which is now a good tier 4, and a decent boost to the ranger, making them a high tier 4.

Also, more streamlined and clarified rules? The rules are just as hard to learn as 3.5 rules are. Clarified, maybe, but core 3.5 was about as clarified as well.

How is that a Balance issue?
If you have a caster in the group you should be buffing the group with the useful spells than be selfish with things like Fly.

Tiers are what you make of them - many seem to like them but over all they are but another way of stating what you think is good vs what anyone else thinks is good.

PF has added quite a lot of nice things to the game and the massive added bonus is that all the important stuff - core rules, classes etc is freely available online.

If you don't like it for the fact that you believe it didn't fix X,Y or Z then you are valid to not like it but that does not make it any less of a great continuation of D&D 3.5
