Will stop gap and "Tenacious Defense" ever work with 1 hp?

i would really like to use the stop gap and also the capstone “Tenacious Defense” with a 1 hp build to achieve full efficienvy. is this possibility considered inbalanced or is there an other reason that this “overkill damage” is not getting removed?
it would open up so many new build possibilities especially for moze

probably not , because it proc after your shield broke and the damage goes thru your hp .

you can already use a level 1 stop gap to achieve invincibility

why a level 1?

because u can use bloodletter to regen ur shield before the 5 sec invincibility gone

ok yea i see
id rather play “fair” and have this mechanic work with 1 hp xD
