First of all, if it's a "small thing", why you make it such a problem? It's a small thing after all.
Also the new skills are not intended to be easy to learn. Doesn't matter if they are available at 110. They are available when you have the rune stones to learn them. That might be even at 120+ or earlier, but it depends. Farm ToI and you'll get them. Only if you don't have a patience to play a grind game, then you can buy them off the market, that's your decision.
I've farmed all these runes over time and I have no issues.
