A realization I came to about Cassiopeia's playerbase as part of said playerbase.
...And that is that we don't agree on anything everything.
One camp of her player base likes Cassiopeia's Twin Fang spam pattern if not the whole rework. They like Cassiopeia's current aggressive playstyle, close range and with high DPS. Some, but not all, like the hypercarry powercurve that was given to Cassiopeia as well.
The other half of Cassiopeia's fanbase prefers her "poison side," and hates the rework because her poison abilities, Q and W, were significantly nerfed, and all her power was shoved into her E. This side pictures Cassiopeia as a "Debilitating champion," wearing away at her opponents with her poisons and, pushing this further, having various debuffs applied to Cassiopeia's opponents depending on how she combos her spells.
Now, I am of the later camp. If I got my way, Twin Fang would be basically scrapped and Cassiopeia would be very focused on melting her opponents' health bars with her poisons, kiting and debuffing them while doing so, machine gun or no.
But I'm only one person and one side of Cassiopeia's fanbase. I realize now that some people DO like Cassiopeia's Twin Fang and high DPS that comes with it.
So, I realize now that asking for Riot to scrap Cassiopeia's E is impractical, and also inconsiderate of a significant amount of her playerbase.
But by the same token though, I think the camp that prefers Cassiopeia's Twin Fang spam also needs to consider the camp that prefers her poison abilities.** If we ask for Riot to put some power into Cassiopeia's other abilities aside from her E and make her poison abilities powerful on their own, that is no more an unreasonable request than for the other side of Cassiopeia's fanbase to ask for Riot to preserve her DPS with Twin Fang.**
Honestly, at this point, I'd be content with Q and W dealing high damage on their own for Cassi's gameplay update. I think some unique debuffs or other things to spice up her poison abilities would be really cool, but I'm not going to push even for that. And even that is not an unreasonable request IMHO.
TL;DR: If you like Cassiopeia's DPS with Twin Fang, that's fine. If you like Cassiopeia's poison abilities, that's also fine. Both sides should consider and respect the other.
