Lissandra Glacial Augment + GLP800

I was experimenting with new runes yesterday, especially new keystones, and came up with these two glacial augment based runes http://na.leagueoflegends.com/en/featured/preseason-update/8300-8351?build=41200238 http://na.leagueoflegends.com/en/featured/preseason-update/8300-8351?build=41200107 Thoughts on Keystones I posted on Boards yesterday about new runes for mages. Burst mages are in a bad spot, DFT mages are even worse. https://boards.na.leagueoflegends.com/en/c/gameplay-balance/K3gTJRwB-bad-runes-for-mages Summon Aeries could work since liss's Q is on a low cooldown, but the damage falls off drastically mid/late game and liss doesn't have any shielding/healing abilities that can target allies. For Arcane Comet, liss's cc makes it easy to hit, but the damage right now is just too low, especially in early game. Late game lv18 when you have 400+ap, one arcane comet does 105+0.2*400=185 damage which is considerable but not much. Phase Rush could also work but I don't think liss needs movement speed since her E gives so much mobility and flank potential. I also don't remember seeing any liss take stormraider back then... Electrocute is a good option and provide very nice damage. It totally fit liss but the problems are 1. other dominion runes don't fit liss (and mages in general) at all. Inspiration and Sorcery are great for mages but if you take Electrocute you have to choose between Sorcery and Inspiration. Sorcery gives you very nice CDR and Inspiration gives you free $600 and a one time Zhonya early game. Both paths are great, that's why I want to take Sorcery + Inspiration. Beside, Electrocute has such a long cooldown early game... I don't think any Sorcery runes fit liss well so I decided to try something new and go with Inspiration keystones. Swap summoner spell in my opinion is pretty useless...Kleptomancy could work, but glacial augment just seems so much more powerful and fun with GLP800. With glacial augment, liss's basic attack adds on to the already existing slow from Q and give liss the ability to play as a control mage while maintaining burst potential. In teamfight, if their team has strong peel/shield (like xayah+taric...) for ad you can build void staff and liandry's to kill enemy frontline (with the movement speed slow which slows down their engage). Or if their adc can be one shots them e in and one shot the ad with slows. The downfalls are that GLP800 doesn't give CDR and that GLP800 gives less burst than protobelt., but I don't think they're that important since liss already have a shit ton of dmg and transcendence + cosmic insight gives you solid 15% cdr and zhonya gives you another 10. If you can grab blue then you have 35%, life's good. I want to know what you guys think about liss's playstyle in season 8 as well as the runes/keystone that best suits her...
