I am going to summarise my thoughts in here about why Priscilla Blessing is NOT game breaking at-all, and here is why
Hater's are gonna hate, so i am not going to rage or care about whoever downvotes
Before I start, I have played about 100 games of Dominion now (not much I know) and 80% of them playing a "full-cap" / "backdoor" role
The advantage is:
1) Takes pressure off your team and puts pressure on the other to stopping you
2) Allowing your game to "buy time" when you're loosing
3) Makes game much more exciting then just fights everywhere
The disadvantage is:
1) The time it takes to capture a point (analysed below)
2) You always are 1 man down in team fights (4v5)
3) You might not succeed if others plays counter / have a simliar role as well, it evens out
4) You're virtually useless if your team is winning
Now having this role surely produces PROs and CONs like I've said, but now let me explain capture time.
Let's name all the points Windmill (Top) being A, then B C D E going clockwise
Assume I am the blue team. Usual start is take D E and fight for A
At any point in game, if A B C is controlled by purple, and a purple champ is defending A, I can always go and cap B.
The capture time is like this:
1) A spots you in map and moves towards B, at the same time you start capturing. With Priscilla Blessing, you neutralise the point, but have NO WAY have enough time to finish the job
2) A spots you in map and moves towards B, at the same time you start capturing. Without Priscilla Blessing, the point remains theirs
No, the point is not mine, but I can ease pressure on my nexus loosing health.
Without Priscilla Blessing, it would be very difficult to achieve such objective.
Note the point is still not mine, but it buys time and makes game more exciting, but NOT game breaking.
So please RIOT, reconsider before taking this item away.
Let me add a couple screenshot later
