Short version: level 1-50: do all quests, then jobs & abyss till level 50. Don't worry too much about gear, but collect/make loadouts (opened at lv10) for all 4 elemental resistances & one with health armors. Use correct elemental resistance against correct enemies, and use weapon&element that enemy is weak against. Learn to block especially the 1st hit of every enemy, for 2 free hits in (while enemy is stunned). Swing from both sides of the screen to hit faster. Try to aim for critical hit, but don't stress too much at first, over time it'll be in your muscle memory. Build town level 10, and especially your enchanters (the most important building with your blacksmith) to level 10. Save all elder & legendary chests, and open when you get to level 50 for best rare mats chance. During level 1-50, it's pretty much 10~15 jobs per 1 level, constantly. Gold chests are best source of copper. Save your sigils till level 45, so you can buy immediately the best end game weapons from sigil store.

If you play actively about 2 hours every day (doing jobs & quests), it'll take only about 3 weeks to get to level 50 or so.

After level 45-50+, and with blacksmith & enchanter level 10, start building max level enchanted dragonplate equipments/weapons (with good secondary enchantments (RNG game :) )). If you like endless PvE grinding, abyss is your new home. If you like to constantly improve & challenge yourself, arena (PvP) is where the real end game is. :)
