1.) Why do I always tank in campaign, even as lvl 60 samurai, when there are 500 paladins who fail at getting party invites??? No cures, no flashes, no vokes, nothing but berserk and dances. I hate campaign paladins. I think Attila posted about tanking as his lvl 60 mnk before lulz. Basically, if there isn't that squad of 10 NPCs fighting and tanking the mob you're engaged on, you will pull hate, and you will die.
While I can sympathize with this, I have to say, wow, you've just had a bad string of luck. It's going to depend on where you go first of all. Secondly, being a PLD in campaign is a lot like being one in a burn party, i.e, people just spam whatever they want, and when they get hit and die they're like "WTF!". Are you really that surprised? If you are, you need to examine yourself before others.
2.) Fugging mages. Summoners meleeing with staves and whiffing, bards whiffing with joytoys and daggers, white mages aggro'ing things and sitting there on auto-attack while you help them out and kill their mob. I, nor anyone I've talked to, has ever gotten a cure before they died in a campaign battle. You should know that you DO GET EXP FOR CURING PEOPLE.
Have you ever BEEN a mage in Campaign? Because I am doing this right now, and I can 100% assure, it's not easy. I do WAY more damage than any of the DD's out there, whiffing away at the mobs, yet I get maybe 1/2 the EXP they do and they're not even doing anything. So you will always see a mage whiffing away at the mob with the DD's because we want EXP as well. Same reason you're there.
3.) Wtf cure NPCs?? Why do NPCs only cast Cure 1 on you when you're in red HP? SE is retarded on this one.
This is going to depend on where you are, how well the nation is doing where you are. If the nation is doing poor, then you're going to get the lowest they can offer. If they're doing well, you'll get the best they can offer.
So I do understand where you're coming up, but, it seems you're expecting a lot more out of Campaign. The main idea of Campaign is what you were expecting, but the players have a tendency of taking the easy way out.
Look at the /BRD's. They're not doing a damn thing, yet for the most part, I don't see anyone complaining, and quite a few joining in on them.
You have to take it for what it is. If you feel you're pulling too much hate, and end up tanking, try toning it down some.
I mainly go as PLD to Campaign, and from what I see in SandyS, there's some good PLD's out there.
