see i feel its all too easy nowadays
Well I don't' think that the heroics are all that easy, considering the way the game has turned from what you mention. Back in the day, You didn't send a tank in ever, without doing a whole lot of ccing, spell stealing and what not (we still have to do that now too though but the tanks are just tougher than they were) but the bosses were tougher too, in that it took a long time to burn them down. Even with the trash in pre BC and even in BC, either a mage would sheep one, another would hex or stun one, the hunter would shoot one to pull it and the tank would taunt that single trash mob before it got to the huter to hold it. The tank wasn't tough enough to withstand 3, 4, 5, trash mobs on them. ONe at a time was the way it was done. I remember that when LK first came out, I saw many 70s that couldn't do the required 550 over all avg dps that Nexus required umless they were in T raid gear from bc and even then, the most dps I ever saw was 750 even with the ones that had a full set of BC raid gear. People were getting kicked due to it all the time. You really didn't even get to finish a nexus run in the beginning of LK until you were around level 74. Today level 68s run it.
It wasn't a one man show though before LK like it is today. Today the tank is usually the one with the most know how in an instance. The rest just have to follow the tank. They don't' generally have to know much of anything except to sheep or hex something as you mentioned. But then in the day, a dpser had to know that too. I think the biggest downfall for the game is that Blizz decided to make it at one point, to where the tank could do it all basically. Pull massive groups, hold them, even heal them self even if there is a healer. No one needs to know anything and really the real only true way to learn something well is to just get your hands in it and do it. But today, everyone seems to rely on the tank to mark his target, mark the ones he/she wants CCd, know where to pull the mobs, know when to pull, and be able to tell everyone else their job. Now in the old days, if you were a prot pali, you were one hard dude to take out in pvp but were still quite squishy to a boss in pve. Today most of my toons can own one. I remember the days I dreaded pvping a protection pali. Usually it took two or three people to take one down and they didn't really need to know how to play one all that well back in those days. Today they are tougher in pve than they were but not all that tough comapred to back then in pvp I know, because I had a level 70 in BC.
I don't think it was really that much harder though then now, but it is differnt. Heorics until you're over geared for them are still pretty tough coming right out of norms. But then again, after this last xpac. it might not be since now you can get t11 with Justice points. Sure wish I knew the thinking behind it all.
