VTC forked away from Lyra2rev2 because both asics and FPGAs were heavily on that algo, to lyra2rev3. There was no network interruption, and that network didn't see a huge return of either piece of hardware yet in a major way.
Forking is dangerous, and shouldn't be rushed. Give many weeks of notice. FPGAs are hard to design around, but not impossible, you needn't become impossible to mine with them, just less easy or way harder to do than other coins to take the target off your back in the short term to be able to plan another fork later on in the long term.
Yes GPU farms have a power advantage and economy of scale, it is only a matter of time before the same thing happens to FPGAs, and then you're in the same situation as before. I'd actually guess that by the time a home miner can't gpu mine with $0.10, your network has already been invested with FPGAs and/or asics.
As soon as your profitability falls below other gpu mined coins, and there isn't any reason to explain it (like much better liquidity causing people to mine at a loss for less risk), then the best explanation is that people are mining on your network using hardware with a much higher hash/watt. If it was a gpu-mined coin primarily then hashrate markets would like zergpool or nicehash and the like would have the bots operating on there arbitraging its mining profitability using rented hashrate until it was in line with other gpu mined coins. The fact that this isn't happening points to fpgas/asics, and it would date back to when the coin first diverged in profitability from other gpu mined coins.
You'd have to be an idiot to think gpu farms are on a coin with $600 in daily volume (according to CMC). A single farm (large enough to actually achieve economies of scale to reduce costs)would crash the price to literally zero. Keeping mining on gpus is a hard goal, it will only get harder over time, ask yourself if you're ready for that fight. If its worth it to keep that low barrier to entry to participating in consensus.
I didn't vote in the poll, I have no stake in either side, but please carefully consider the what the raw data implies for your specific case and history, not just generalities.
