For example your reapers are in lower ground, and the enemy’s peon line is on higher ground next to them, so you use the Surveillance Station to reveal the terrain over the reapers and they jump and destroy your opponent’s economy.

Sounds easy, right?

But I’m referring to when they’re trying to get back up.

In order to traverse over a valley, the new changes make it seem as though the reapers will not be able to make it to the other side unless they have a “spotter” kept at a previous altitude. Here’s an ASICC art demonstration:

the valley:
_|…|_
_|…|_
_|…|_

reapers:
x

Reapers above valley on one side can jump down to the lower:
1.
_|…|_
_|…|x
_|…|_

2.

_|…|_
_|.x.|_
_|…|_

But once down, they cannot ascend up to the other side because they do not have the vision to see what is above them:
_|…|_
_|.x.|_
_|…|_

So, in maps where such valleys are narrow, such that a reaper on one side of the valley can have vision onto the other, a spotter reaper will need to be kept on the previous side of the valley grant passage.

1.
_|…|_
_|…|x
_|…|_

2.
_|…|_
_|.x.|x
_|…|_

3.
_|…|_
x|…|x
_|…|_

To reunite the reaper group, the group will have to wait at the new end for the spotter to make his way over and return to the group.

1.

x|…|x
_|…|_

2.
_|…|_
x|.x.|_
_|…|_

3.
_|…|_
x|…|_
_|…|_

My point in this new balance being: in order to traverse terrain, clumsy maneuvers like these will have to be employed. To bring another spotter unit like an SCV or medic seems troublesome in large maps where there may be many hills and valleys so that SCV’s and medics take a long time to get to the desired ’spotting’ zone. Reapers, in my opinion, should be able to cruise around the map on their own without this clumsy restriction.

“To my disbelief, the Medic inside the Bunker was healing the SCV outside of the Bunker.”

The blog does a great job putting things in context, exactly for the purpose of informing even those who don’t follow each and every update religiously. You just have to trust them, I guess. =)

Also, I disagree about the reapers – I think it adds a nice dimension to them. Don’t forget that other units can give them vision too. Worst case scenario, you sacrifice an SCV to scout ahead (while pulling off a diversion on the other side of the enemy base).

All that assuming that this is really the case, since Karune (as usual) was a little obtuse about his words.

Yup, this will be great for Reapers to back door, or in team games for Stalkers to Blink to strategic positions.”

This isn’t clear to me. Is it *necessary* for the reapers to see over the hill to fly to it? This wasn’t the case in the playable demo at blizzcon. If this is the case, as the blog seems to assert, then it seems to me that the maneuverability of the reaper has been over compromised. Medics cannot traverse over higher/lower platforms so they cannot follow the reaper in his path over really texturized terrain. I can envision terran players clumsily separating and holding reaper groups for ’spotters’ so that reaper groups can traverse over valleys and hills. … That sentence didn’t make any sense †_†

Flame comment:
How does sc2blog deal with these commenters who do not know what they’re talking about?

Matrix — “So what if a 3-4 pixel line obscures your 10 pixel unit for like 2-3 seconds? You aren’t gonna die or lose just because of that.”

Yes. You will indeed die or lose just because of that. This occurs even at the amateur level of play.

Medics and the bunker:
Yes. Karune did explicitly state in an old announcement that medics can heal OUTSIDE the bunker. Scroll down a few entries on the sc2blog to read about Karune’s personal encounter with this balance change.

I don’t know why I’m clarifying these points. If you guys haven’t done your research, chances are you won’t carefully follow updates in the future and will continue to yield useless posts. I worry that your frequent ignorant voices will flood out the voices that have educated things to say. I mean I suppose there is some merit in having these extremely lay person posts heard — in that Blizzard can learn to be clearer in the messages they send, and in that understanding the concerns of the lay-person Blizzard can internalize how to better market to this consumer bloc.

But still! Your uneducated assertions on the game drive me mad.
*This* consumer has followed every update since the game’s announcement, and he is quite satisfied with the evolutionary direction developers have taken the game.
