Since introduction of the DHS there has been much debate about the exact value they should have.
In my understanding the design goal of PGI for DHS could be summarized like this:
“DHS should really improve heat dissipation, but not allow heat to become a non-issue.”
Adding to this, we have the famous “3s to core” argument from PGI which somehow indicates, that design goal here is also to avoid an unbalance toward light mechs.
The situation as we find it currently is as follows, Engine integrated DHS up to a maximum number of 10 work with an efficiency of 2.0/0.2, additional DHS outside the engine or beyond the maximum of 10 work at 1.4/0.14.
This results in the following
- Light mechs with large engines benefit the most from DHS.
- Assault mechs with small engines and large number of DHS benefit far less from DHS
- Light weapons produce relative less heat compared to damage
- Heavy weapons produce relative more heat compared to their damage (exception being the large laser)
I find this somehow contradicts the design goal as I understand it.
But I also do not want to change the entire weapon balance heat complex. I would like to stick as close to the current balance and only do slight modifications. After some simple calculations I would like to suggest setting the heat efficiency for all DHS to 1.9/0.19.
Here is a short table (sorry total noob to BBCode based tables) based on 10 DHS attached the engine.
Total Number DHS Current Build all 1.8 all 1.9 all 2.0
10 20 18 19 20
11 21.4 19.8 20.9 22
12 22.8 21.6 22.8 24
13 24.2 23.4 24.7 26
14 25.6 25.2 26.6 28
15 27 27 28.5 30
16 28.4 28.8 30.4 32
17 29.8 30.6 32.3 34
18 31.2 32.4 34.2 36
19 32.6 34.2 36.1 38
20 34 36 38 40
After looking at his table, I think the design goal could be better suited with all DHS set to 1.9/0.19 instead of the current mixture of 2.0/0.2 and 1.4/0.14
In my opinion the following points speak for 1.9/0.19 and against the two other possibilies:
- Negative effects are limited to a 5% and only for mechs with 10 or 11 DHS.
- A broad range of builds benefits.
- Benefits are moderate. Only from 19 DHS on benefits exceed 10%.
- As benefits are moderate, even for builds with a real high number of DHS, the possible freed tonnage is also limited. Thus it prevents a 4xPPC Atlas transforming into an 5xPPC.
