F2P MMORPGs are probably the worst about this. There's so many different and completely detached-from-each-other premium currency and progression systems designed to keep you spending money in all of them.

1. Mine and Smelt Ore to smith a Weathered-state weapon.
2. Imbue your weapon with a special stone granted during PvP events to give it elemental damage.
3. Upgrade the weapon at the Whetstone to increase it's stats up to a maximum of +10.
4. Login daily or complete premium radiant quests to get special fairy dust that gives the weapon another mythical boost to it's stats for 24 hours.
5. Go to the barter NPC and trade your Weathered weapon for a Pristine one for even better stats.
6. Complete guild quests to gain a blessing of the guild for your weapon to even further it's performance.
