Welcome to FT asbery
Unfortunately you're a bit late with your ire, unsurprisingly this has been covered in depth since 16th November where you could have joined in with the other poor, small proportion of folk who perceive their miles to have been devalued
You'll find that your case is far from typical, so you should perhaps not suggest that your advice is followed universally. However for your flight patterns, it does seem like the program is less favourable than it was, so perhaps you should look at another program now, if you can find that is more suitable, I suspect all your extra Easyjet segments have earned you somewhat less in terms of usable miles
You may also want to look into the reward savers offered, as these offer you significant savings on short haul redemptions, which if you're using Easyjet (therefore not flying long haul), will be a valuable option for you
