3- Subs or not, the pattern & behavior is the issue, not subs. Look at the number of 24hr bans on his account. Also keep in mind that he has attempted to join on alts after receiving leaver bans.
When you write unbalancing, do you mean like super stacking? Because unless the substitute player has the exact same .rws as Memory does, it inherently will become unbalanced. Just how numbers work, ya know.

When it comes to point 3, RWS isn't the only thing we should consider, i looked up the W-T-L of MeMoRy for his 125 last pugs (first 5 pages with 25 pugs each), if we only keep the ones with low kills and death (the ones he left soon or joined late), here are the figures :

Page 1 1-1-8

Page 2 1-0-5

Page 3 4-0-5

Page 4 2-0-3

Page 5  4-0-5

For a total of = 12-1-21 when he leaves soon or join late, if we'd take the time to exclude those he joined late (at least 60% of the wins are off the table)

Still, if we consider that he joined late maybe, 20% of those times (34-7 (6.8) = 27), 27 pugs on 125.

Means he rq's soon 21.6% of the time. That's without taking into account when he leaves mid-pug, late pug and in ot.

In comparaison i looked up my own recent 125 pugs, 2-3 pugs per pages i had low kills and death (all of whom i joined late, at 1 time the pug died soon), for a total of : 5-0-10.

Which is comparable to his page figures, in term of W-T-L. But for the same amount of pugs played, he left early or joined late 2.26 more times then me. His 50 most recent pugs (page 1 and 2) are what is worrying, 2-1-13 thats a soon rq 32% of the time that leads his team to defeat 13 times out of 16 (81.25%).

So his behavior of leaving everytime it doesnt go its way is far from recent (looked up his pages until page 10), but his behavior of not caring it unbalances the pugs is.
