A prioritized and hopefully realistic Wish List for 2.13

[CUnknown]

I have two questions for the more experienced players:

1) Are games often won without the use of SC's?

2) Are games often won without the use of lifedrain in any form?

If the answers are: "No, not often. You typically need SC's and/or lifedrain in order to win competitive games." Then, it seems reasonable that lifedrain (in any form) should be either nerfed or made more expensive. Doesn't everyone agree with this, even the people who are against nerfing lifedrain?

If people answer "No" to those questions, and still are against nerfing lifedrain, I'd like to hear why. In my opinion, the less viable options there are in a game, the less strategy there is. So, nerfing lifedrain in Dom2 would make other options viable, and make the game even more deep than it already is.

Now, I'm not sure if lifedrain is tyically necessary to win, so I haven't made up my mind about nerfing it yet.
