So the whole health pack thing should be considered greatly...
On one hand, more health packs encourage more elaborate bombs and faster game play, but at the same time hugely devalues the medic position, and I feel may lend itself to be more focused on a dm fight as opposed to team coordination. I feel this way because, if we look at the game in terms of that phases of pushing/defending, it essentially means that you can instantly bomb after defending as opposed to getting arrowed/resub. I think this may reduce team strategy because if you want to transition quickly from defense to offense (so that whoever died on the enemy team's offensive endeavor is has not yet respawned), you may allocate someone to be prepared to have 4 rockets loaded and good health to bomb. If there were more health packs (especially on the ramp as indicated in the img), that role would essentially disappear and defense would become more of a clusterfuck. I'm not really sure what you guys have been seeing in terms of defense in EU, but generally from the PUGs we've been playing in NA, defense can turn into all the soldiers bombing in a big group and its just a huge mess. So I'm not really sure how this will change if you add health packs, but I do think that adding health packs reduces the skill necessary to successfully transition and complete intricate bombs. On top of that, one of the decisions the team has to make is whether they run a med or not, and by adding these health packs, medic loses a lot of a value because the med is not as important during the transition from defense to offense. Not playing with a med should be significantly more difficult because you gain the advantage of having another person who can bomb/frag, and I think adding the health packs drastically decreases this opportunity cost. It still should be tested though to see how significant they actually are, the more health packs may not be so significant.
Also, yeah, if med is eventually banned for some reason, the health should probably be added, but I think you guys may be missing out on the power of having a med... He can be really strong in terms of scoring and acting as the point guard.
On another note, the changes about the trimp ramps should be changed and I think you're right about the airblast things, they shouldn't be a hassle to use.
There was another map (made by Laxson) that we were testing that had water in it and it was a really cool dynamic to bombs, I'm just not sure where they would fit in the context of Jag's map.
