Unit selection should activate sooner, when selecting with the mouse

[oblio]

When I want to micro multiple units, you'll use keyboard shortcuts. But sometimes you want to use the mouse selection: left-click + drag over the units.
Currently there's some sort of glitch, making it hard to select units this way (I tend to miss the selection much more than in Dota 1 and SC2 or other strategy games...) .
At first I did not know what was happening, then I decided to study the problems. And these were my conclusions

I'll explain:
When you want to select units with the mouse, you can start from 2 sides - top or bottom:

I tested with method A, from the bottom corners - this seem to work ok.
But with method B, from the top corners - this doesn't work ok. Unfortunately it seems I'm a natural B user

Some in game screenshots for comparison, from Dota 2 and WC3:

I've barely reached the treant and it's selected.

The selection box has passed over half of the treant, but the treant is not selected.

Basically, this makes my type of microing much harder/annoying. I know about the keyboard shortcut for unit selection, but sometimes you will just need the mouse selection. And currently it sucks

Yeah I've noticed this also. It seems to happen sometimes with even much more than half the unit selected.

On a semi-related note, The position of the mouse click is very awkward as well. It seems to be significantly above and to the left of the actual mouse point.

To me it's actually the reverse. Sometimes I convert with enigma and end up moving everyone instead of just him or just the eidilions. Might be a case of getting used to it.
