About to play a game with Unsealed Spellbook
As a support. Hope me luck. I'll let you guys know how it went.
######I say hope because it's a waste of a wish...honestly, it's a waste of hope too. Just save your hope. And your wish.
In my mind, I see this rune being extremely broken, so I'm sure I'm gonna go into this game and 1 shot everybody while roaming everywhere and winning everything.
Edit: Game 1 didn't go well. We got counterpicked; Me (Lux) and vayne into xerath ashe. Lane was rough and we ended up losing the lane (didn't really feed though). Also everyone else's lane ended up losing, and they had voted 4/1 at 15 mins to ff. I pressed no because, like Lux always says, the superior tactic is to never give up. (Thanks for keeping me positive Lux) Anyways yeah...I gotta try again. Will update when I do.
Game 2: Lux / Ez vs Kalista / Tahm. We won our fights, got a few free kills on some people early game; didn't matter. 1 gank from the already fed Kayn proceeded to 1 shot us (in .46 seconds) and push our turret down. Game went on for a while; darius got fed too (yay 1200 damage ults and kayn walking through the jg walls literally 1 shotting everyone) prior to that, having flash and ignite up so frequently felt pretty useful. I like the 25% CDR so far, but I haven't found a point where I'd want to switch summoners (since I use hexflash, it's up even when flash is down, and if you switch while something is down, it retains the CD, making switching from ignite to something else really pointless) I think it would be more useful if you could switch and have another SS ready to go; or maybe at least reduce the CD. Trading SS sounds useful, but if you're only doing it to wait for the original one to come back up, you can't, so it becomes useless. I might try again.
Game 3: Lux / Draven vs Varus / Blitz. We were pushing, getting good poke in. Level 3, draven decides to leave lane for the crabby, takes long enough for 2 waves to push up, and I end up dying. I end up rushing boots and roaming, and I helped get top / mid fed. Game dragged on for a while, and while flash saved me a couple times, I probably wouldn't have been in the situation where I needed it up so fast if I didn't go down this rune path in the first place. I did eventually exchange ignite for ghost just to outrun the enemy akali / rengar, but the keystone really didn't feel useful in this game. Our riven had it as well, and I only saw her change it once for a few mins, then back again, and she didn't even get a chance to use what it was she switched to. I've come to the conclusion that it isn't unsealed that I like as much as it is hexflash. It's just too useful for roaming if you're playing a champion with CC.
Overall, kinda mixed. It's hard to say if it's that good or not. 2 mins off flash is pretty nice, but if flash is down, it's still useless, and I dont think changing spells is useful unless you're changing a spell thats already off cooldown. Probably good for early game pressure on champs like annie, or good for escaping those frequent ganks, but mid game, if everyone's grouping, it really feels useless. I think if you wanna go down the inspiration path, just take klepto or glacial augment. Way more effective.
