Rek'Sai has Serious Issues
is supposed to have map presence which is why she's weak in other areas.
However, until level 6 she has absolutely nothing but weaknesses. Her damage is heavily gated and I would rather you just took the true damage away from her E and give her sustained DPS like you already have with her Q. You're basically splitting up her damage between sustain Q, gated E, and long cooldown+enemy immunity W. Why make players fight against their own character? And honestly you could just take away the damage from burrowed Q as it's clear you just want it to be utility and put it into another ability that Rek'Sai needs to actually duel. Q is useless during a fight and is again primarily utility.
I mean seriously, what the hell is the reason for gating the abilities of a character with lackluster damage? It's understandable on
who is capable of insane burst but not
. It's as if you think that her "global" map presence is so strong that she has to excel at literally nothing else. What exactly is she going to do with her presence? Fart voidlings on her enemies?
Speaking of presence how is she supposed to be able to sustain said presence and endure trades in fights with the antithetical scaling of her W? The healing isn't remotely useful during a fight as she has to remain burrowed to utilize it. The healing costs her fury which makes her E basically useless so she cannot go back into the fight until she builds it up again (which requires her to be in a fight she can't sustain or output enough damage in to win or live).
can get fury quicker than Rek'Sai, and his heal has better efficiency.
Rek heals for 25 health at level 1 and 450 maximum at level 18 (if she has full fury).
Tryn heals for 80 health at level 1 and 300 maximum at level 18 (if she has full fury). Tryndamere instantly gains fury with his ultimate meaning he can heal for 600 health mininum at level 18. Rek has to build up her fury again (with no attack speed steroid again) and again if she wants to heal she's not going to be outputting damage where as tryn can output damage while both healing and gaining resources to heal.
Given that you'd expect Rek'Sai to have an infinitely better heal than Tryn. She doesn't and "map presence" is not a justified reason why considering she can't do anything with said presence unlike
,
,
,
,
, or hell even 
And if she's supposed to be mobile (see: out of combat) then why the hell does her fury dissipate after 5 seconds on not gaining any?
The design of Rek'Sai is insanely counter intuitive. I can't think of a single other champion that works against themselves in so many ways.
It's no wonder "Beat Punchbeef" never designed another champion before or since Rek'Sai. The incompetence is unfathomable.
maybe 3 but
has fallen out of favour. at least on the
level.
