Far more interesting and viable options for the Resolve runes on the second tier.

Frankly, the second tier of the resolve runes are quite frankly the worst I've ever even seen given as an option. Those runes are weaker than current low tier MASTERIES, of which we can take 10 as well as the current runes, let alone the insanity of the new runes in literally all of the other trees.

Gold values of most of the new runes across the board tend anywhere from 450 to 1000+, and then these resolve runes sit at 250ish. Lategame, after you have gotten the items to amp them. Early game they are worth about 60-70 gold. The only one that is even remotely decent is conditioning, of which it is still comparitively bad, just the least-bad of the 3 options.

Here are some ideas for some runes that can go into those same slots that fill the same basic ideas.

1. Turtle Shell - Start the game with +20 armor/MR. Lose 5 per 5 minutes until 20 minutes. This gives us an early game focused rune that will decay to non-existence, for cases where you have a hard lane that you just must survive. If you can't make the impact of that early time work in your favor, then the rune's value to you is lost entirely, but can easily help you survive in the early game, or perhaps enable a bit more early aggression.
2. Runic Warrior - While above 75% HP, shields and heals applied to you are increased by 10%. While below 25%, regenerative effects are increased by 33%.
3. Conditioning - This one is fairly decent enough IMO. We'll leave it as is. It has a clear purpose, in that survive early game and gain permanent bonus defenses.

EDIT : Just remembered another rune idea I was thinking about. A rune that would Increase base armor by 33%. Considering how armor works, it would be a fairly tank focused rune for netaging ADCs a smidge by resisting the LW line of items, although it would ultimately even lategame be only +30 armor on the bulkiest of base armor tanks at about 30 armor, a 600 gold value. It's value would be more from the fact that it resist LW and such, making it a good anti-ADC rune, but wouldn't work as well vs Black Cleaver, and would be a rune that heavily depends on base stats (meaning you don't have to worry about it being abused by champions it wasn't designed for).
