As I have been reading this and the other posts, I am starting to agree.
1. I don't want to have to have multiple characters or have to grind thru them.
2. I liked the dual spec in WOW, but not in Rifts. The ability to change anywhere negated groups from thinking thru who they were taking.
3. I agree with those that speak of PvE spec vs PvP spec. I like to PvP also, this makes sense.
Some want to Tank and DPS. I want to stealth and heal.
What we need is to have the ability to switch classes. Or have a class-less system completely. Then you can do whatever, where ever and as fast or strong as you want to.
It can even be level-less so then we can just pick the skills across all the classes and mix an match them. Then we clould have an SI wearing armored pants (that look like CE vendor Armor) with Flamethrowers and stealth ability that can heal at will.
This solves all the issues I have heard on why we need dual specs while fixing the issue of not enough Tanks and Healers. It also makes the 'solo only' people happy.
