What makes you think they aren't? Mine are lvl 162 so would suggest they can go to 165?
The arcamon themselves aren't technically capped, but foods say on them what level they can be used until.
XL foods only work until your arcamon is 159, any higher than 159 and it won't accept the food. I also have 162 pets but that's due to the last food getting it from 159 to 162 in a single shot. Since there are 5 stats that can be levelled, the theoretical limit is 164 (159+5).
I'd say rather than incrementally increasing cap on foods a bit at a time each time there is a level cap, do it in jumps, so maybe wait 1 or 2 more level cap increases before bringing arcamon up to match. Otherwise it's just more balancing work for Andy to deal with when I'd rather he spent that time developing new content.
Foods capped at 160 When lvl cap and mobs was at 160. Now there’s 165 mobs and players, surely an xxl food should be introduced. The fact u got lvl 162 pets is because u done ur maths whilst feeding ur pet. I’m sure Andy had not intended pets to go lvl 162.
