This is my first ever thread. I hope this is the right place for it.

I have an EUW LoL account that I barely use (main reason being my ping, and that I have another account on NA). I've played quite a bit on it, not ranked. Account is probably 7-8 years old (made it with the NA account that I play on atm), it's missing a few champions that were recently released (and a few old ones that I don't like playing). So out of the 141 current champions, it's missing 11 champions (Azir, Kalista, Kindred, Kog'maw, Malzahar, Quinn, Sejuani, Talon, Vel'koz, Xerath, Yorick). It currently has 1309 blue essence and 101 RP on it.
Proof of account: (I blocked out my name and 2 of my friends' name on it. I'll clear the friends list.)

Skins: Screenshot
There's purchases made on it. I have 1 ultimate skin (pulsefire ezrael), 3 legendary skins (zombie brand, primetime draven, and brolaf), 10 epic skins (project zed, soul reaver draven, mecha kha'zix, mecha aatrox, dragon trainer lulu, dark star varus, iblitzcrank, warring kingdoms xin zhao, arcade sona and tyrant swain), and 96 other skins including lee sin, vi, zyra, lucian, caitlyn, ahri, evelyn, diana, zed, riven, yasuo, miss fortune, shen, jinx, udyr,etc. It comes upto around 12k RP (minus the free skins I acquired from chests). (Sorry for not capitalizing, I gave up on that.)
It only has 6 emotes: Screenshot
I recently got back into OSRS, obviously with no money on it, but a few decent skills like 87 mage, 82 cooking, 72 fishing, 65 wc/fm. I wish to continue on it.

I know I'm new, so obviously I have no right to request the other party to go first, but I'm just afraid of getting scammed.
If I've made a mistake in the way I posted, or even posting in the wrong section, I apologise in advance.
Please let me know what amount this account would be worth for, and I'll accordingly (after due consideration) reply.

Regards,
Mark
