So I’ve gone back and forth on this.
When SOTL made his video discussing a mod that did thus (among other changes) initially I was supportive.
In general the SEA civs were struggling on the ladder, and many of those civs had some other relevant bonuses, so it seemed it would help struggling civs while also being thematically appropriate.
Admittedly the Khmer, Vietnmaese, and Burmese all had UUs that would overlap with the elephant archer (and the siege elephant in the case of the ballista elephant). However I thought, and still think that could possibly be addressed with some stats tweaking.
Since then however
- In general SEA civs have been buffed. Khmer had their ballista elephant armor tweaked. I think overall it was a buff. Burmese changes are basically a meme, and not all changes were unambiguous buffs, but finally they’re an averag-ish civ it seems. Vietnamese and Malay were buffed big time overall over the last two patches.
- I looked more into how SEA civs historically used elephants and they primarily used them similar to what the battle elephant unit is. Not as rams or archers as was the case in india.
So as of right now I’m not particularly receptive to this idea. SEA are all averagish civs so they don’t need a buff, their inclusion wouldn’t be historically accurate (which isn’t the end all be all in a game, game design should be the driving principle but if we’re going to be historically inaccurate AND it doesn’t solve any problem then it’s just bad all around IMO), and lastly the issue of the Arambai, Ballista Elelphant, and Rattan Archer competing with those units would still have to somehow be addressed.
Best case scenario, you end up trying to fix civs that aren’t broken anymore, by adding a historically anachronistic units, only to give yourself the new problem of making sure their UUs don’t conflict with those new units.
As someone who formally was very favorable towards this concept, as someone who championed it in forum threads and youtube comments, I believe at best it’s an idea whose time has passed, at worst a very stupid idea that never had any merit in the first place.
That is a generalization over the four civs though. The burmese would have the best case historically for their inclusion, and the malay would have no overlap with their UU. I don’t think that makes it a GOOD idea for those civs, but generally the argument for adding elephant archers and siege elephants to those civs is stronger than it is for Khmer and Vietnamese.
