"Minor" rules changes

[Lefty X]

No Arcane Spell Failure.
Full Attacks as a Standard action.
Some system wherein casters add their casting stat bonus to spell effects.
Pulling the 5 tier alignment system from 4E. (Which feels stolen from 1E Warhammer anyway.)

Do any of these things feel, legitimately, like they would make the system go blooey?

[Cheapy]

Yes.

All of them but the alignment one.

[Darigaaz the Igniter]

Yes, all of them.

I like my dual axis alignment

[Ashenfall]

I dunno. I might enjoy my wizard having a 40 AC while pumping out nothing but empowered maximized quickened magic missiles that add her Int mod to the damage of every missile, followed by the argument of whether my Int mod adds to every die of chain lightning damage, or only the total.

I'll allow it.

First and third rules are outright broken. Full-attacks as standard actions would simply increase the mobility of every martial class in the game. I think it would be most overpowered for ranged combatants.

Single axis alignment could work, it's just very boring and doesn't fix anything.

Allow me to add a caveat.
It's an E6 game.

[Ashenfall]

What's E6?

[Lefty X]

Alternate advancement system. Google it.
Short version: Level normally until 6th level, then you get an extra feat every 5000 exp. Every five "Epic" feats, and your level for CR purposes goes up by 1.

[Elven_Blades]

In that case, not nearly as bad.
What's the Ability Score Generation? Point buy, 4d6 drop low, dice pool?

As a full 20 level, I would say "Hell no"

Also, maybe just improve caster armor by one step ( wizards no spell failure in Light armor, ect.)

Alignment not a big deal no matter what you decide. It doesn't have much mechanical effect on the game, aside from a few spells you would have to re-work. Since you are a doing an E6 game, I think that might only be Protection from (alignment) spells anyway.

[Lefty X]

We use 22 point buy.

[Marius Castille]

My EK would love the first three. It's free up his arcane armor feats!
