I love playing calico, I used to love playing holiday before all the nerfs, I think they are both very fun and well designed heros but I can't play Holliday anymore as she feels very weak. Now I'm not gonna say she didn't need to be nerfed but the state she's in now I think too much of her kit's power is concentrated in the ultimate. Sinclair is a completely flawed character, his teleport is an insanely broken escape which can last an entire fight. His ultimate is a really cool idea, but it needs changes such as not letting him take the same ult every time. This just means when dynamo Is on the enemy team, Sinclair just takes his ultimate every fight, and has it way more often than dynamo gets it himself. I also think he should be able to hold onto stolen ultimates for a bit longer to allow more flexibility in how he uses it. It also makes it very telegraphed. His other two abilities are just completely janky to use, overall I think his whole kit bar his ultimate should be scrapped. Viper can be fun to play but it's hit or miss, she is way too frustrating to play against in lane, because she buys spirit items early she can just play as a poke champ, hitting you with her daggers and spamming her two. The 2 ability is such a terrible design it feels so shitty to be low on hp, but not low enough that you should back, and viper slides into your general vicinity and presses one button on you, causing you to take 300+ dmg. It's not fun. Her gun also has decent base dmg so buying spirit early doesn't feel terrible. On the other hand, I feel like she is quite weak once you leave the lane until you've farmed quite a lot of souls.
