Should I buy her? OR is she as worthless as everyone says in normal/ranked games and buy Renekton instead?

she's currently pretty broken. All her spells rely so heavily on placement, that it requires you to be in the thick of the fight, but she is too squishy with poor escapability to be in the thick of things

you are likely going to get nothing but negativity about the snake from the community....buy her, master her, carve a niche for yourself, await buffs, dominate....

I disagree. Her ult is buggy, yes, but it's not her main damage dealer in a fight. She requires good positioning, and deals a lot of damage if played right. She's definitely on the more difficult side to play.

Regardless, you should try her out first before deciding if you want to purchase her or any other champion. Free champs change every week, so you'll eventually get to them.

I agree with psych. The only buggy part of her is her ultimate, which I don't even know why they haven't fixed it yet. I mean, it's REALLY buggy. You can cast it right in front of the enemies and it may not even hit them.

She's an interesting champion in that she's a DPS caster not the heavy burst type that is so prevalent in the game. Unfortunately, DPS casters don't really work because teamfights last too short for them to get their works in properly. Her damage output is theoretically very good though.

Where Cass shines is early game. Her passive lets her combo some mean harrass without going OOM so fast, and her spells hurt squshies. She starts to be a bit useless midgame but then comes back strong late game if allowed to farm up.

Having said that, I would not recommend her to new players due to how her skillset works. You really need to nail down the concept of proper positioning and skillshot aiming to do well with her. Those two things take a lot of time and practice to get. Other casters would not only be easier to pick up, but also let you enjoy the game without feeling like giving up.

I feel like Cassiopia is just about the most common champion I've seen in the last week; it is odd.

The usual recommendations apply: don't spend your IP/RP until you've played her during the free week and know that you like her.

Thanks everyone for your inputs, I've actually tried both Renekton and Cassiopea during their free weeks. I liked them both even though I lost all the games I played with them (which is around 3 games with Cass and Ren). It seems like Cass will be a challenge to master, but what are your opinions about Renekton?

Tanky DPS is king these days so Ren isn't a bad choice...

Do you enjoy sustained nuking via E + poisons and domination with Q in lane and having a unreliable buggy ult?
