Hello, thanks for commenting on my guide. I'm actually new to mobafire and how it works, also I didn't quite finish the guide. It was more for a friend and I ended up explaining them further elsewhere.

I have tried Iceborn Gauntlet, and I find that it really depends alot on how the team is performing. If the team's doing alright then the aditional damage from iceborn is a good pick and the passive works well in teamfights. But if the teams are even I consider frozen heart to be the safest item since it gives more armor and decreases attack speed. However, it too depends on your own playstyle, either item works well depending how you play, regardless of team performance. I personally like to be in the front line of a teamfight as to distract enemy damage from my carries, so Frozen Heart gives me the better tank stats I need to survive long enough to heal.

As for the runes. I also use Sorcery runes but I didn't know how to add a second rune page in the guide. I take Summon Aery, Manaflow Band or The Ultimate Hat, Transcendence or Absolute Focus, and finally Scorch. I pair it with Inspiration, Perfect Timing and Cosmic Insight. I've also tried using the Resolve runes but they don't work as effectively damage-wise and you're far more dependant on your team than you already are using the other runes.

The matchups vary really, but you're right, I didn't go indepth about the tank matchups in the guide (that part I explained it further to my friend directly). I definitely agree it's really easy to poke and burn down tanks, they're actually the easiest matchups. However, I'm kinda in a low elo I guess? whatever elo gold 4 is where they match me with previous seasons plats and diamonds or whatever. In ranked people would be very cautious but still be poked down easily, in normals they die easier. But in both cases most tank matchups end up building tank items that help them sustain from your damage output, so they either die or recall, but eventually they outlive the amount of damage you can do before you run out of mana. Karma top may come out as a surprise sometimes? maybe? But an experienced top laner will either roam or coordinate well with the jungler. So while the tank matchups might be the easiest in early game, they might become a problem nearing mid and late game. So in a tank matchup your focus should rather be in how to build yourself depending on the enemy midalaner and adc, since you can pretty much survive and kite the toplaner tank damage already, you ought to mind more how your midlaner and adc are doing, who they're up against, whether the enemy team has more ap or ad damage, warding the entrances to your jungle, etc.

After the runes changed all I did was play karma top since it was something I was already used to play before the update and because the new runes made her even more interesting to play, and I actually climbed back to gold only playing karma in the top lane. I do need to play different playstyles though, but I've played enough to be able to tell what worked for me the most, which is what I tried put together in this guide. I'm glad you liked and I might not update the guide in the near future but I'm fine continuing the discussion here.
