Caitlyn's ultimate needs more reliability

She's so incredibly outdated right now, most matches i see her contributing nothing, i feel like every other adc outclasses her right now. Back in the day she was the safe lanepick/win champ who outranged everyone and was messy to go against, oh and the legend says, she countered vayne.

Anyway, what i'm most annoyed with is her ultimate, the completely useless ultimate 86.345% of the time, it's obvious this ability was taken dircetly from DotA's Dwarven Sniper, and to add some originality riot made it blockable which makes it (in my opinion) useless, i mean she's a rifle expert sniper lady and has a slow as f execute ability that can be blocked by 200 hp braum if the player can react faster than a sleeping sloth. Executing/sniping enemies should be what cait is good at, yet jinx can aoe execute way better than cait, and the enemy might not even know where the hit comes from, i mean really now?

Since i've been writing this discussion for 5 hours now while simultaneously playing, i'm just gonna get to the part where i make suggestions for changes.

1. Remove the blockability/ make blocking reduce damage by X% for every champion it passes through
2. Make it an instant cast/an enhanced autoattack which could crit(with reduced crit dmg) and apply onhit effects.
3. Remove the indicator; i mean really, it's a sniper shot it shouldn't be "hey you, i will shoot you now, from right over here"
4. Make it % max health true damage (just kidding, enough of that bs) One of these should really happen and would make the ulti more reliable and give caitlyn the signature she needs, because right now, whenever i see her i expect her team to lose because she brings nothing into game compared to other adc-s.
