@Riot let's take a step back from arcade,star guardian,pool party and............
Come back to the lesser skin lines that could use some new additions
I'm really happy that they touched again on the dragonslayer and omega squad skins and am hoping some of the other older or briefly introduced skin lines will also make an appearance. The one I hope for are:
Academy The academy adventures are full of great ideas for this skin line and I hope that riot would expand more on this universe as much as do for arcade and star guardian
Arclight/ Justicar A very creative whatif skinline depicting dark characters completely flipped and from a brighter perspective. It would also be interesting to see the opposite happen and see what the brighter champions look like as darker versions
Battlecast and mecha
I've been trying to find any good ideas for a
skin but then it came to my attention that she is the only voidborn without a battlecast skin( an oversight I hope is rectified) as for the mecha , it can apply well to any number of melee weapon champions
Dragon Trainer
If riot can't do a dragonslayer/master skin for
or
then I'd settle for this skin line
Elderwood For the love of all that is good decent and sacred please can we get some along this level of goodness https://orig07.deviantart.net/d2a2/f/2016/208/1/4/143eb203b2321e70cdbd69b7e2468101-dabncuo.jpg
Headhunter
Finding good matches for headhunter is about as easy as finding good matches for blood moon; they got to have the potential to be menacing and terrifying. Not to mention have skills , equipments or personalities of good hunters:


Marauder and Warden One of my most favorite skinlines that also gives homepage to the league lore before the retcon by being linked to the main aspects of summoners rift
Worldbreaker and worldweaver These Aztec/maya inspired look very stunning and has a nice duel quality like wardens and marauders in that there are two opposing sides ; breakers and weavers
Cops and robbers
The cops can go to any number of Piltover champions like http://68.media.tumblr.com/bc1772dbbea84cc2a437d0bfbc2a93db/tumblr_olbrg7cmME1tirp9oo1_1280.jpg
And seeing as
and
have attempted to robb the Piltover bank in lore, why not skins to go with the theme like https://vignette3.wikia.nocookie.net/leagueoflegends/images/6/64/Evelynn_SafecrackerSkin.jpg/revision/latest/scale-to-width-down/640?cb=20170616012335
Special individual inclusions: dunkmaster
or
, prehistoric
( triceratops), order of lotus
, bloodstone
, hired gun
, Woad
, jedi 

would look amazing. (Zyra, obvious. Skarner is the other bug champion so he would fit in the trio with elise and kha'zix, stinger could be a thorned vine like zyra's melee plants. Rek'sai isn't really a bug, but if anything her and the xer'sai are more bug-like in design so it could work maybe? Illaoi's tentacles could be vines, but maybe elderwood would suit better? Urgot could be a flower man with his legs being pedals and vines pull his target in.)
