She is the same if not worst.
The buffs WONT solve the previous problems because of 2 reasons
1.Sombra only gets value out of stealth,
Stealth is a reposition tool, an ideal situation would be , stealth—go to backline—get a hack/kill
she cant get hacks reliable because of bugs and hack cancelation
she cant get kills reliable because of inconsisten dmg.
2. They dont adress sombra main problem which is
.Her value in midfights
and
. BUGS , I dont think i need to explain myself here A list of Sombra's Many, Many Bugs (6), Now with more LOS Bugs! - #22 by Bendubz11-2740
Thats why it wont fix her but intead this rework adds nerfs like
.Destructable translocator
.Slower Stealth
.No contest
IN A NUTSHELL: Same problems, New bugs , NERFS> BUFFS
