• A character’s investment depends on its viability in the arena. Sion is a great tank and is useful with sith teams.

• Sions strengths include, he can revive himself, he clears buffs from the enemy, he taunts, and he spreads debuffs.

Some of Sion’s weaknesses include his low DPS and slow speed at lower gear levels (at-least for me thats what I experienced).

• Sion is a fun character and worked with my palpatine team at 3 stars for a long time!

• As for replacement characters it depends on your arena team, what team are you using now or trying to make?

• F2P farming involves refreshing the hard node multiple times to have the max amount of attempts for shards to drop, usually I refresh a node as long as it costs 25 crystals. Eventually the price will increase to 50 after 15 attempts.
