Terrain ideas

Ok i need ideas, or better sketches of a terrain for my game. The game is about two team of undeads that fight against each other. I can terrain rather good, but the problem is I need some ideas how to make strategically great terrain. The battle should take place in a necro styled environment: ruined city, sever, graveyard.

SO please if anyone has any ideas, sketches, whatever; I would love to hear/see them.

I say you should look at some screenshots of wow, preferarbly, stratholme, andorhal, and scholomance. Been awhile since i played but i think looking at those will give you an idea on what your looking for.
But for strategical terrain, make everything equal. Look at melee maps for help with that, thats what i do if i can make things precise and keep it cool looking at the same time. There are quite a few melle maps that are very equal to the destroyed / necro style, maybe base your map slight on those?

@ shadowy-crafter: Tnx but no thanks, I need something a bit more serious. Tnx for the suggestions, anyway.
@ Zeal: melee maps it is...

It's not out.

Strategically you can do a number of things. Mostly their pretty ovbious:

Choke Points: Every team should have at least one of these. This is an area which is easy to defend, for one or a number of reasons:
There is a tower there.
There are hills there that ranged heros can get on to easily and fire down onto units below.
It is small and units cannot pass easily.

Raised land. I don't see enough of this, just a small hill of cliffs to give ranged heros a slight edge when standing on top of them could be a really powerful strategic tactic. The 25% chance to miss when attacking uphill is very nice.

Ambush areas, areas with narrow windy paths coming off the side, preferably both sides. These paths should be impossible to see down and are great for laying ambushes, either by lying in wait or by charging out to catch an enemy off guard.

In the same, there need to be boltholes, escape lines through the debris that allow a hero to flee with relative ease, unlike the ambush holes, they should be quite wide and open to give the fleeing hero plenty of room to manuver. However, don't overdo either these or the ambush lines, too many will just result in chaos.
