I have 4800 IP and I was really thinking about getting a new champ. I don't have a really defined main or a role that I like, although I do have a thing for the more complex or mechanically difficult champions. I have 
and 
in the 4800 range already and 
from the 6300 range.
I'm kinda torn between buying one of the higher tier champs like 
or getting 2 lower-cost ones like 
or 
Any suggestions?????
Link Yt2 votesAdd me on league and message me and i can help you out. I need to get an idea of your play style and such to tell who would be best tbh but I usually do good at helping with what champs friends should buy. If you like mechanically challanging Champs then Fiora, while easy to survive with, is hard to master but fun. My best tip for fiora is - her repoist can stun if she is cc'd by anything during the cast, so against high cc champs shes really strong, and ALWAYS go for the mark, even if its behind them. It heals enough to make it worth and the Q an make it a lot safer because, when it hits the CD is reduced and then you can use it as an escape if needed.
AcidTheWarlock1 votesThanks, I added you.
Targon2 votesI recently bought Orianna with IP and she's really fun. Has lots of options with her kit!
Shadowlord909092 votesI would say it depends on what role(s) you are intereseted in. I can briefly summarize all the champs you listed. I will also sort it by role.
Midlane: Talon: He is a very bursty assassin that has interesting stealth mechanics kinda weak atm but still fun. Azir: A champion that can be very good if played correctly but there is a learning curve in order to pull off more of the technical moves. (Shurima shuffle) Katarina: Probally one of the most hated midlaners due to her kit which can result in "Insta pentas" she is very easy to play and even if behind if she catches up she can carry a game. Vlad (Top/mid): Vlad has been nerfed recently but he is still pretty strong. With his empowered Q it allows him to have a lot of sustain in lane. Lane game he is tanky and can turn teamfights around with a well placed ultimate.
Top lane: Fiora: A very fun champ who can also carry a game, with her ability that allows her to reflect stuns and block abilities, other than that I do not know much about her.
ADC: Kog' Maw:Very fun champ but has a weak early game due to the lack of escapes in his kit. Most of the time he will be camped by the enemy jungler so try not to overextend. But late game this champ is a monster. With his "turret form" he shreds everything ranging from champions to towers. Draven: The champion played by the notorious Tyler1, draven can be a beast mid/late game with his Q almost two shotting enemy carries. He is a very fun adc but you need to practice catching your axes while in a teamfight. he also has a global ultimate.
Jungle: Evelyn: A jungler not seen too much currently but still can pull her weight. She is known for her stealth which basically puts her kit together. She is an ok assasin.
In conclusion I reccomend Katarina in the midlane, vladimir for the toplane, draven for the adc, and khazix for the jungle if you are looking for a good assasin.
Azure Hamster1 votesIf you want a tricky mechanic ADC, check out Kalista. I'm a Cait main (I love range... I play Hammer in HotS) with 465k mastery points, and I am so fucking bad with Kalista it's amazing. Really, I suck bad with her. (And Vayne)
deadzombie9181 votesIt all really depends on your level of play (low level, unranked, low elo, high elo, smurf, etc.) Here are my recommended Champions for each role. Top: Fiora (her W - Riposte is the only skill in League of Legends that can literally negate all other skills, stunning if she negates a form of cc), Riven (considered to be one of the hardest Champions in LoL, only one player has truly mastered her) Mid: LeBlanc (outplay queen), Zed (outplay king), Ahri (play-making queen) Jungle: Rengar (stealthy, bursty champ capable of 1-shot killing anyone without a Thornmail or Armor items), Kha'Zix (read Rengar desc.) ADC: Kalista (do not soloq with her, half her kit is disabled without her Oathsworn) Jhin (heavily reliant on skillshots and his 4th auto), Ezreal (extremely poky yet entirely skill-shot reliant, Kalista can decimate him) Support: Leona (one of the best Supports, having the best gank-setup at Level 3 with a root-stun and a teamfight-changing ulti) Soraka/Sona (heals for days and fight-changing ultis), Alistar (the tankiest Support in LoL with his ulti, and a hard engage/disengage kit)
If you have Leona/Ashe bot, Ahri mid, and Fiora, Riven, or a toplane with CC top, Master Yi is a very excellent Jungler to use, having amazing synergy with CC-heavy teams. Also Talon is excellent as a mid or adc (I've seen a Yasuo ADC in LCS)
