While not familiar enough with Saga to know what you are looking for - what 'unfashionable play style' do you feel 4E is somehow against?
I have found the 4E class building system to have a remarkable level of versatility and customizability. The opening of skill access and former class features via feats allows one to adapt to almost any character concept they might have.
Most complaints I've seens have been built around, honestly, mechanical concepts, like not being able to play a Rogue who Sneak Attacks with a Greataxe. That isn't a character concept, and I don't feel there is any fault in a system that lacks that potential - as long as one can play a stealthy thief who slices people apart with a greataxe, which is an entirely viable concept.
You mention being frustrated that others forced your fighter to act as meat-shield - that is a group problem, not part of 4E. It is no different than 3rd Edition clerics who wanted to fight in melee, but got told to sit in back and heal the group. Each class can generally fit into several roles, even if they have some specific ones they default to.
Fighters are Defenders with a bit of Striker, and can just as easily be heavy-hitting warriors as meat-shields. If you want to play a Fighter as a damage-dealing machine, the system is more than ok with that - the only thing standing in your way, apparently, is the group you play with.
Sure, you could assemble a fighter/rogue/sorcerer/druid/bard/wizard, but... what does that mean? What character concept is that?
Pretty much any genuine concept you could build in 3.5, you can build in 4E.
