Am already QR Gold, but quick history - was CX Gold, but when Marco Polo changed to Club Points, I basically escaped to QR. But recently, QR also devalued their Qmiles like crazy. So I am looking for some advice on whether I should stick to QR or move somewhere else on OW. Some advice is appreciated!

1) What is most important to you in a FFP?
from most important to least:
a) even lower fare classes earn decent Qpoints/Club points (ie. If I buy a lesser fare class, am not stuck with 25% or 0% and screw up my tier earning abilities)
b) business class redemption upgrade using points/miles (ie. not like QR now where you earn tons of miles but can't redeem anything)
c) using miles to book flights with minimal taxes/fees
d) op-up

(2) How many miles do you usually fly each year & in what class? How many flights/sectors?
100,000+ miles, but split between Star Gold and OW Sapphire. Around 85% economy, 15% business.

(3) What types of fares do you usually buy?
Higher-fare economy for club points

(4) Can you choose your airlines and/or class of service? Do you travel for work and/or pleasure?
Yes, I can choose. My usual OW airlines I fly on:
QR BKK-DOH-Europe
BA BKK-LHR-Europe
CX BKK-HKG
JL BKK-HND
Never flew AY, but open to it

(5) What is your home airport?
Bangkok

(6) Do you have FFP status of any kind in OW or other airline? What is it? Do you have any miles banked in a FFP?
QR Gold/OW Sapphire
TK Elite Plus/Star Gold
