to Mata :
I do not know if in Tier1 is in secondary profesion max 400CP, because I do not reach 400. Maybe if I reach 400, it will change to 400/500 as for other Tiers.
As for miner it is not so hard to reach 600/600 especially in Tier4 ( ingots are needed also for making T6 ingots ) and Tier5 ( ingots probably
will be needed for future T7 ingots ), I found most hard to reach 600/600 for woodcutter and also not needed, because demand for wood is only from weaponer and extremely little from armorer, but ingots are needed in large quantities from all crafters - armorers, weaponers and also jewellers.
Of course you can buy ingots , but my investigation
makes evident that in almost all times is financial better to dig as buy only. Just now market is little unbalanced because many players are waiting for T7 ( including many miners ) and because nothing to do - they dig and dig ..... and dig .... and dig ...
... so prices for ingots are just now extremely low.
