1. We changed the way the flares work, more into a weapon than a utility.
2. afaik in the past we had problems with it, IMO its still not working that well, due to limitations but its userable in its current state.
3. dunno about that, dont remember any one saying it was hard coded...
4. it wasn't possible cos of huge texture problems which a guy from DICE helped us out with. I wouldn't say 4km^2 is super huge. I have crated 16km maps but the biggest problem there is rescaing the textures to fit that size, if you work out how to do it, please tell me, but it most likly means editing the terraindata.raw file of the map by hand, which I have tried many times in the past with a hax editor and not got it to work

Still with 4km maps we have dynamic shadow probs on the terrain etc.
5. dunno when we ever said this was hard coded?
The fact of the matter still stays the same, ie, to acchive these things we have to do HUGE work arounds for most parts to acchive this kinda stuff, and it dose not work perfelcty due to it. There is no simple little option that you hit for us to acchive this stuff.
"fastropes" techinally is not hard coded, techinally its already ingame as you can deploy a grapple hook from inside the chopper, then jump out the chopper and jump onto the rope. We have known that for ages, the fact is this system dose not work at all well and is very buggy etc. There is also no other better way we know of doing it at this time. As a result, for the same reason DICE abandoned the fast ropes in there mid development stage was cos they couldn't get it working very well, and in the end of the day, it offers nothing to gameplay since the chopper ingame can much more easily land than do the fast ropes.
