she certainly isnt as fast as other assasins when it comes to single target burst but im preety sure that her is also among the highest even if we wont take her full ultimate channel into account
I assumed we were talking about her QWE + a maximum of 2 daggers coming out from her ultimate. There's absolutely no reason it should be up for more than 0.5 seconds.
the only thing that is that lb talon fizz or other bastard will do their combo and score a kill in 1 second or less
kata might take 1.5 to kill (which is much longer when we look at the timefram assasins work in)
They also have the cc or utility to follow up on those kills if the initial burst fails. Katarina has less initial damage than them, and less followup damage when they escape, supporting the whole "she can't contribute to a fight until someone is already essentially dead" argument.
but taking objectives is in itself an opportunity for enemy team
As I said, even if the enemy team takes that opportunity to engage, it's still a 5v4 + some katarina Qs and will still be in the team of 5's favor. If the team is pushing and gets pulled by a blitzcrank, or a nidalee spear chunks the adc, or a fiddlesticks ults over the wall to flank them, of course they're going to lose. But simply pushing an objective doesn't give the other team that much of an opportunity, the pushing team has to willfully put themselves in danger with no vision control to actually lose that much, which isn't necessary to starve out the other team until they have to leave or contest a disadvantageous fight.
and its not like katarina cant compete to the game without going all in on somebody
She's only contributing ranged Q damage, which is laughable to the front line, even with luden's echo.
Not to mention it isn't exactly a long ranged poke, the risk of getting close enough to Q an amumu, or a vi, or a malphite, or a warwick isn't worth the damage.
as i said its all strategy, can work both ways even if executed propertly
If one side executes properly and the other doesn't, the side that executed properly will win, I think we can agree on that. What I'm saying is that going off theoretical potential, if both team played completely properly, katarina's team would lose every time, because they do not have the pressure to deal
and the entire strategizing went down the drain
its all weird and unpredictable crap on top of other weird and unpredictable crap
fact is that katarina can randomly decimate your team because something happened ... and everyone hates that
every champion has counteprlay but katarinas sucks quality wise
This is the key aspect of why katarina is seen as overpowered by less skilled players and trivial by the best players. Her true counterplay isn't a champion, or a spell, or an item, it's playing perfectly. If you play perfectly, katarina does not do well. It's that simple.
Yes, when katarina is shutdown in lane, she can still comeback and pentakill late game. Yes that can be frustrating, but you let it happen. The reason you didn't actually "shut down" katarina by killing her a few times and denying her cs in lane is katarina's damage even with ks and kills is sub par. Her damage potential isn't optimized by items and levels, it's optimized by resets. And resets are always available and on the table. They're easier to get if fed, but kat is "shutdown" and the enemy team is playing poorly and disregarding her, of course they'll be able to get a reset and unlock more damage.
If you look at this and say "well what's the counter then if shutting her down in lane isn't fully effective?" The answer is to not give her opportunities for resets. This is where the diverge in skill level comes. Not giving her the opportunity for resets shuts kat down whether she's 5-0 or 0-5. Giving her the opportunity for resets snowballs kat, whether she's 0-5 or 5-0. A katarina can almost always be useful against a poorly playing team. A katarina can almost never be useful against a proficiently playing team.
That's why kat players get frustrated when people say she's overpowered when she's one of the only champs that you can shutdown even when fed, purely with good play. Katarina can only do well if her team is obscenely ahead or the enemy team does not play well. Those are the only possible conditions. Katarina can't carry her team against a team that won't give her opportunities for kills.
This is very unique counterplay and very unintuitive. Most people are used to looking at a score and saying "I don't need to worry about that champion, they're 0-5" or "Wow that champion is going to be a huge impact, they're 5-0". Katarina doesn't handle like that, but as I've mentioned several times, that's a double-edged sword.
Snowballing from behind or getting shut down while fed are both realistic outcomes for katarina, unlike a majority of champions. People just only like to focus on the 0-5 comebacks and shout OP, and claim the 5-0 shutdowns were because the katarina player was clearly just bad and couldn't carry their team. Both scenarios exist, but you better believe the lower skilled players make a bigger deal out of one more than the other.
