Your hashrate changing isn't related to what we are talking about. I have no idea how or why your hashrate changed, but it has nothing to do with how profitable or unprofitable a coin is in general (unless you switched to Aeon or something, in which case your hashrate change is super low, it should have doubled AFAIK). YOUR hashrate is about the algo and your hardware's settings (or the pool--if you're overclocked and were previously only earning 270, you weren't on the best pool), not the blockchain. The hashrate we are talking about is the global hashrate, which is a key factor in determining profitability, not each individual hashrate.

The point is that difficulty/reward and market value are what determine profitability (difficulty and block reward determine total coin payout, market value determines the coin itself's worth). Your hashrate determines how much you contribute and are rewarded (directly if in a pps or pplns pool, indirectly if solo mining). Your hashrate does not change based on the global hashrate (a 1.15TH S5 still mines at 1.15TH today, it just earns less than it costs in electricity now, whereas it used to earn a lot).

And your knowledge of GPU mining is also way, way off. My gpu rigs were, dollar for dollar, easily the best investment in mining I've made, and STILL earn in the $15-20/day for me, which is currently more than the X3. Yes, overall the rigs were more expensive, but they've also been running continuously for more than a year and are well past the profit point. With ASICs, unless you bought in the first round, you're lucky to break even (unless you have free electricity or the coin surges).

All of the above said, my second best investment was my L3+, and my cpu mining rigs are actually doing pretty well as well since the monero algo fork. It's all relative.

And you don't need to be so defensive about all this, feel free to ask about things you might not understand, we all learned that way (and MOST of us are friendly around here).
