Well, OP has a point. Changes can occur, but Turbine seems to do them with no aim at all. Now ward, now don't, now ward.. Same goes for classes, roles, feats, everything.
A nerf is sortable. Let's say, the new "hard to kill" ward (The name itself deserves a post). I have a Pale Master. Not a one trick pony, I hate those for every single class. In fact, I think one of my favourite spells is Web, and now that I think of it, I'm a palemaster who plays as a tactical wizard. I can do the same with a WF AM. I don't like sorcerers JUST because of the closed spell lists. But, while not a pure-instakill caster, being a PALEMASTER means you study the arts of necromancy, and focus in that area. Since the spell selection we have in DDO is limited when compared to PnP (in which is too wide, by the way), instakill is the logic option. And here's the point:
- They took time to create and develope (thus, less time spent in other stuff) creating a prestige class (or enhancement) focused on Necromancy, which in this game mostly translates on instakills.
- They develope the game further to epics, and now decide instakills is not really an option.
See? Do NOT add instakills from the beginning, and you won't have people complaining about it when you suddenly decide to take them away. Same goes for everything, decide what game you want to offer, so people can decide wether they want to play or not.
Are pale masters still nice? Sure, lich form is a boost to DCs, and it adds self healing if you have no access to WF race. I'm not only talking from the pure gaming perspective in which you only consider numbers and math. I'm talking about the MEANING of the class. A wizard who focuses so much on death spells as to "become" a lich... but can't kill stuff because now mobs have a blanket inmunity? What's the point?
And this only considering the pale masters, but not everything pivotes around the melee vs caster's eternal war. Now you have more builds and classes affected. Divine casters, assassins, monks, etc (Assassins is another great example of not having sense to implement just to negate them one of their major features, if not the key one).
And sure, you can bring the following argument: "You can still play casual or normal epics". Well, yes. I can. Even hard or elite, just casting different spells. But the point will still stand: Why create a death-focused PrE to negate them their key skill in end game? What's the point of taking time in developing a Tier 3 PrE to not be "fully capable" in all of the content? Why create a rogue tier3 PrE with an instakill option, just to take that instakill out of the equation? I mean... hello? we have like dozens of bugs and unfinished PrEs out there. People have been waiting for druid for how long? And meanwhile you creating PrEs that you plan to render semiuseless on endgame (which is your new toy, by the way)? This smells like a lack of planification. Go ahead, state what DDO is to you, what DDO is gonna be once and for all, and stop wasting everyone's time (yours developing, ours preparing useless builds/paying you).
I still play PnP. With some DMs, I know they don't like this or that rule, so they change it/ignore it. You know that, so all is fine and dandy. Either you agree and play, or you don't, and don't play. Sure, some DMs have an easier time finding people willing to go by their rules than others. But which ones have no audience? The ones that change rules in the middle of a campaign when a player performs one particular action they did not foreseen. And that is what Turbine seems to do now.
