Dark have you play tested crit chance runes on Tryndamere?? Serously try it it's simply op compared to ad flats, or ats flats. Especially on Tryndamere criting is his bread and butter, doing that early game will allow Insane snowballing early on compared to ad or ats.

Well, there's that you will get SLIGHTLY reduced cooldown on E with crit chance marks. SLIGHTLY increased damage on Spin with AD Marks. SLIGHTLY increased movement speed with Attack Speed Marks (animations are shorter).

But that doesn't really matter...

That's not quite what I meant at all. There's more to figure than simple raw damage calculations and calculations with armor fixed in to figure dps for the physical rune types. I'm going to work on this and pm you when I've finished.

...it's actually fairly simple to calculate chance when searching for DPS:

100 AD
50%critchance
200%crit damage

100 x (1+0.5) = 150 Average damage.

As you said, you'd rather have more chance to crit then doing more damage overall. Okay I guess lol. Well I think there's nothing more to be said. At least now you know that other runes give you more damage.

However you might wanna know that attacking more often also means you have more chance to crit :P

Well here's the thing, all of those calculations are relatively close in number. It's hard to calculate chance because you never know when that difference in chance will come. What I'm trying to say is that I'd prefer a greater chance to deal more damage than to do a relatively close amount of damage using different marks on base attacks.

lol o_o.

I'm a bit inebriated atm. Allow me to calculate in the pm tomorrow.

I could try Armor penetration for level 1 as well...

Against 200 Armor: 710.09 Average DPS


It seems They are all very close late game. AS Marks are clearly the best for jungling and AD Marks are better for early game laning. If you're looking for late game damage, go For Armor Pen or AS... or crit chance as your 3rd best choice.

I think that's all.

I'd like to see your maths sure :P. When I'll have the time (tomorrow surely) I will do them as well.

Let's assume we have full rage bar already (35% crit chance) and compare the damage increase of crit chance marks to the damage increase of AS/AD/ArPen Marks. I'll do it for level 1, level 9 and lvl 18. If crit chance marks come out to be the best then I'll bow ^_^

@ DarkPercey:

Bud, I can do the math for you as I have done in the past to prove their worth early game compared to the other possibilities. I didn't put them in the list without reason. I mentioned CrD because that's what your damage becomes when you crit and AD runes don't increase the chance to deal CrD.

Simply put, no lol. Just do that maths. I don't know why you're talking about critical damage ._ . No one mentioned it lol.

If you're in lane, AD Marks will make you more powerful early game so you can get fed and win the game.

If you're aiming for late game damage, Armor Pen marks will give you deal much more damage late game than anything else.

If you're jungling, Attack Speed marks will make your rage bar go up much quicker than Crit Chance marks.

And in lane, just last hit a few creeps and your rage bar will be full, regardless of your AD/AS/CritChance/ArmorPen/CritDamage.

Crit chance marks simply never are the best choice...
