Hai guys! So I've been deciding on a champion to buy lately to refresh the fun in the game for me (cuz' experiencing greatness with "new" champions is fun for me.) I tried Shyvana this week and I found her to be very fun and frankly, beginner friendly (imo). But in the end, I decided I wouldn't buy her yet for some reason (mainly unsure if I would do well with her afterwards in Summoner's Rift or not after playing her in Twisted Treeline).
So now I'm deciding if I should buy Brand, Zed, or a 4th rune page - because rune pages are always fun. Reasons? I like Brand's unreasonable burst and his overall simple playstyle. Also, burning things is fun ( Blaze + Liandry's Torment op). I considered Zed because my brother commented that I'm decent at mobile champions and that I need an AD mid laner (which I do). And of course, if I don't want either I end up buying a rune page for versatility and ranked preparement.
Why am I unsure about buying what? Tbh, I'm leaning towards buying Brand mainly because Zed is so much more high skill capped compared to the rest of my champion artillery and his nerfs make him unattractive in my eyes. Of course, I know that Brand is really easy to counter and that Zed has a lot less counterplay. Right now they seem like opposites besides having burst.

What do you guys think? :o
