Can anyone that is a Wizard tell me what is the best reason to be a Wizard and what is the disadvantages?
Weak as hell. Low HP and physical defense.
Strong as hell. High magic defense and you always get first hit at least by casting magic at a distance even against aggros unless they stray near you and start attacking first.
If you can kill things in less than 3 hits you won't need any healing because usually by the time they can attack you've already killed them.
Wizards in most games are characterized as physically weak, magically potent. PW is no different there. However, a wizard in PW is not as strong as the wizards in most games. Their damage does not offset their very long channel time at all. They're not a popular class and most people would even say they suck. Pretty much everything a wizard can do, other classes can do better. DD = archers, healing = clerics, tanking magic bosses = robe/light support clerics and venomancer pets, zhen = easily replaced by another archer, and so on. They can do a lot of things, but they're not really the best at anything. At level 89 and 99 they do get a lot better, but so does every other class.
However.. wizards have a lot of skills, and many of them have effects that in combination with each other can be used to achieve many different things. Stuff like slow (doesn't work as potently on flying players), blind, knockback (doesn't work in pvp), damage over time, seal, half magic/physical damage, lots of AoEs, and eventually they can stun. It's not your stand and spam a single button class; you need these things. So if you like casters, but don't want to stand and spam a single skill to level up (like a caster veno does), and would like more challenge than a cleric, that would be when you pick wizard. xd That, and if you like backstabbing people in PK or watching a huge group of squishier builds die all at once in a territory war to one of your AoEs (level 60+).
The best reasons to go Wizard are: The damage, and the animations.
Disadvantages I can think of:
Low HP - Either, you follow a Pure or an Light Armor build, your HP will be low, making you very vulnerable and being able to be killed with just a few hits. It starts being annoying at the beggining, but the more you level, the more the problem starts to being reduced, as you get equipment with +HP, or you start using HP shards, etc. And at high levels, 89+, you can get a pretty decent amount of HP refinning your items.
Low Physical Defense - This most likely just applied to the Pure build, since the Light Amor build is able to get a really good amount of physical defense with Stone Barrier. The Pure build is able to get a decent amount of it, once it starts refining equipment.
PvP - In the early PvP, like from Level 30 up to 50 or maybe 60. Wizard's are an easy killeable class (unless you got very good equipment), making it difficult for them to be good at PvP in the low-mid levels. But the higher level they get, the better they do at it. (NOTE: This is just at PvP, at TW they start shinning since level 40 or so).
Getting a different role - By this, I mean that, there're many times when in a party, a Wizard will be ask to do the "healer" role. This kind of botters many Wizard's, so I consider it a disadvantage.
Advantages
Different Elemental Damage
Strong Magic
Cool Skill
Can level up without using charms (meditate save money)
Disadvantages
Slow casting time
Healing sucks badly
Weak Def
Low HP
Meditating? O.o I don't know why you'd wanna pick that over charms on a wizard. My 6k MP is gone in about 1.5-2%, and there's a heal spell for hp. Sure, you can stack on mp regen [I do that when I can't find mp charms for sale; people sell cheaper than gold trade for those].. but it slows you down a lot.. I still run out of mp every 3-4% doing that. Wizards are no less reliant on mp charms than clerics. O.o Their charms can last longer though (especially when zhenning).
Morning Dew doesn't suck that bad lol. It fully heals you and makes a good backup heal for bosses that hit your tank hard when you can't find a 2nd cleric. By knowing when to use it you can eliminate the need for hp potions.. but it's still recommended to have an hp charm for pk/pvp and if you get critted/aggro'd.
light armor and hp build.. very hard to kill but lower damage output
hard to lvl the first 50 lvls but gets a bit easier after that,
we can sneak upon players an kill them before they had the chance to hit a bit and the armour looks really cool with females
Wizards are pretty self sufficient and work well in party.They got the heal and if you kite the monsters properly you won't need to heal too much.
