I am against the nerf for several reasons.
1. This does not discourage megabases, but promotes it. You now have to build 1.5x bigger to get the same amount of scrap per cycle. Bigger bases mean more lag, which is one of the biggest issues with servers now. The main reason why I do not go past a certain amount of planter beds is because I cannot process the scrap fast enough without needing to buy more recyclers. The current bottleneck for a lot of players is recycling (hint: more recyclers = more money) and crafting, not planting.
2. It makes it harder for casual players to make more net worth, while barely affecting the "whales". The jump from 100k NW to 1m is a 10x multiplier. Above 1m, every extra million feels "pointless," as at this point you have basically infinite self-revives, and can do all the player spawned helis and bradleys you want. Nerfing orchid rates makes that first million way harder, while everything past it remains effectively the same, creating a greater disparity from the new players who ration out their unlocked self-revives vs those summoning 50 helis at the start of wipe.
3. It does not diversify the way of generating scrap, (which in turn increases net worth). Orchids still blow everything out of the water BY FAR, nerf or not.
4. Folks who grinded to, say, 300k orchids this wipe to make 900k scrap, now need 450k orchids to make 900k scrap hit that same threshold. That sudden devaluation of orchids and hours feels far more discouraging to people who played the previous wipes and then want to play again on the new wipe. This can cause a section of the long term player base to quit, as they do not want to put in more effort to do the same amount of work they could do previously.
