Skills: Pre 3e you have percentile (Thief) skills, NWP slots or no skills at all. After 3e you have only trained/untrained. In 5e you have skills with granular proficiency, just like in 3e, except the math is flatter.Very few of the mechanics resemble 3e.
What would make it more Advanced in your opinion?Doesn't look like any sort of D&D I would ever play. Basic=boring.
What would make it more Advanced in your opinion?
I overall have to agree. It looks like a fairly elegant system I would not mind playing.
It looks like a playable system.
Making characters less mundane.
I generally like the way to customize PCs. I can always add in options.
1) They've reduced the power curve far, far too much. You've got almost the same skills at Level 1 as Level 5. Your to hit is almost identical. Etc.
2) Class dominates your character to a far greater extent than I want it to. If you want a skill monkey (even a knowledge skill monkey, or an acrobatic skill monkey) you pretty much have to be a rogue. Fighters are going to be insanely better at fighting than anybody else. Etc.
3) Lets totally go back to glass cannons. D4 hit points for wizards? With all that damage? No. I kind of like characters to live.
