well it is very easy to farm it
what is gating you is how slow it is to get anima / honor for all those upgrades.
people here on forums very often confuse "Easy " with "fast"
for example gearing up via combination of hc raids/m+ and arenas is relatively fast - its objectively very difficult and hard - but its "fast"
gearing up via farming batttlegrounds/anima ? its extremly easy - but at the same time - extremly slow (epsecially if your play time is limited to 6-8 hours a week like normal people play ) and capped at 197 itlv.
