The T2 transport changes are heavy-handed IMO. AFAIK, they're designed specifically to target T2 arty drops, which we all know are extremely strong, but nerfing the transport movement speed does significant collateral damage to various aggressive drop playstyles that I feel strongly are NOT currently overpowered:
- Com Drops (was already nerfed heavily with T3 ACU bp changes)
- Sparkies
- Early T3 land unit drops (different game stage)
If I'm correct that the goal is to nerf arty drops specifically, I'd propose that T1 arty be given a "drop cooldown" that prevents them from firing for 2-2.5x their typical reload time after being dropped from a transport. You could also potentially add some small movement freeze (1-3sec). That increases the response time before they begin doing damage, allowing typical counters like LABs and T1 bombers to get in range before arty DPS is being applied. This could have some interesting consequences, like incentivizing people to mix in some tanks for instant DPS application.
If the goal isn't only to nerf arty drops, and other aggressive drop strategies are also intentionally being targeted, I really question the logic of that. Sparkies, T3 ACU drops, etc. are all expensive and extremely scoutable, and T2 transport speed was already nerfed from having parity with interceptors.
