The first 2 items are absolutely useless. They both work better the more you die, which rarely happens for high lvl players and sounds great for low lvl players, except they don't have the cash or coins to waste on temporary items. Since spawns have been made less random, being invincible when you spawn isn't that great, might be alright on occasion, but not worth paying cash and coins every so often for a minor advantage. Kamikaze kinda sounds fun, but it would have to have a pretty large radius and do great damage. And even then it can hurt your teammates too, not that helpful.
