So, unless you only every play one character, you need your rune pages to be pretty generic or you risk taking a useless one for a new char.
What do your generic rune pages consist of?
Mine are not finished, and are just here as an example of what I'm looking for. I leave comments below them to let people know what I have in mind for the build.
DPS:
13 Armor Pen, 29% Crit Dmg, 3% Crit Chance, .86 Health Regen/5
Quints are Armor Pen. Reds are Furor with one Crit chance, cant decide if I want them to stay crit damage or not. The rest of the stats are just speckled around. I was in the process of remaking this, and then got lazy (DAMN YOU RUNE COMBINER), and just left it alone.
Tank:
6.5 Health Regen/5, 2 Health Regen/5 at 18, 175 Health at 18
I just started building this one and don't have all the runes for it yet, so if it looks incomplete, that's because it is. I don't stack MR or Armor because those to me are specialized stats. It would be a waste to stack a ton of armor and have to worry about 1 Melee and 4 casters. That's just my opinion.
Caster:
5.2 Health Regen/5, 2.0 Health Regen at 18, 29 AP at 18, 5.48% Cooldowns
Another one I'm not sure of. Health regen is good for staying in the lane longer in the early game, thats why i take it. The rest is obvious, just can't decide what I should sacrifice, if anything, to get more cooldown reduction.
