Hate to be the bearer of bad news but to be completely honest I highly advise changing to any main other than earth.

Ive been playing for over a year, personally I like earth and really want to use him and to that end have spent a fairly embarrassing amount of time trying every conceivable team, but compared to every other main he is so weak you are severely handicapped using him.

-Has 2 possible debuffs, ignition (with his chase) nice addition to damage but igniting one unit for 1 round isnt gonna make a difference in 95% matches/

immobile but since this is a passive skill slot used to replace a standard attack you have to go into fights with one fewer perk than other classes.

-He can consistently make shields, but unless you have about a 30k power advantage over your opponent the shields will withstand at best 1 hit. Plus with the gnw treasure now out and most players using atleast one shield/buff cancelling ninja shields are more irrelevant in the game than ever before.

- He is the only main without a useful designation. Since 3.0 he has been classed as "blood limit" but since there isnt a single character in the game that buffs that earth yet again has access to one less perk th*l the others

Lightning- sword

Water- sword and now senjutsu

Wind- senjutsu ( could maybe argue female too, with her very useful flower guard)

Fire- secret jutsu user

- Is the only main with no healing/health recovery/leech skills whatsoever.

- Since 4.0 has 2 passives that increase def and resistance with damage taken, but the increases are so little that even with both passives active unless you use him with a very specific and boring triple healer team and keep him alive until atleast round 6 the increases again arent going to make any difference

TLDR- unless you are willing and able to spend thousand of pounds on characters like 6 tail naruto, kage tsunade, edo hashi etc earth simply isnt a viable for any aspect of the game other than story missions.Literally every other area you will be playing with a handicap
